In this blog, we will review the concept of resistance, resistivity and steps to calculate the minimum cross-sectional area and diameter of any desired conductor.
What is Resistance?
The property of a device or a circuit that opposes the movement of current through it. Resistance is measured in Ohms (Ω). The resistance of any material with a uniform cross-sectional area is determined by the following four factors:
If you are a first-time online learner, taking an online course or even considering one you may find that they can present some unique challenges. Without a plan for managing these challenges, your performance could suffer. Here are 5 tips to help you succeed in an online class.
The holiday season is almost here, and we wanted to update you on how the holiday break will impact our technical, tutorial, and administrative support.
The Student Support Center itself will close at 10 pm on Wednesday December 23, 2020, and will reopen on Tuesday morning, January 5, 2021.
In this blog, we will review the theory of Magnetic Fields and its basic concept. We all know that magnets exert forces on each other and its magnetic force is distributed around. Magnetic field lines are used to describe these forces around the magnet. We understand that magnets have two poles and that depending on the orientation of two magnets there can be an attraction (opposite poles) or repulsion (similar poles).
Covid19 has brought with it a number of changes, with social distancing and work-from-home measures becoming common. At GBCTechTraining, these changes mean that while our online programs are still available, George Brown College has closed its physical buildings to most staff and students and we are working remotely. As a result of this closure, you are now able to access your Certificate online as an eCertificate, in addition a printed copy of the Certificate will automatically be mailed.
The beginning of this, the third decade of the new millennium, may have started out rather bleak, but it does not mean that things like innovation or advances in technology have come to a grinding halt. In fact, quite the opposite is true. As we find ourselves in the midst of the Fourth Industrial Revolution (more commonly referred to as Industry 4.0) the adoption of automated machinery in the manufacturing sector shows no indication of slowing down.
Online education has brought numerous advantages to learning, such as making education more accessible, and in some ways, more interactive and engaging. However, it has also brought some unique challenges. Feelings of isolation, difficulties with self-direction as well as time management issues are common among students in online courses. Students may feel isolated if there aren’t resources or opportunities available to interact with faculty or other students.
Online programs can be a challenge for students, especially when the lack of in-person interaction is paired with learning new and unfamiliar technology. Our team has worked hard on creating a number of platforms and tools to help students become a part of the community, build professional relationships, and discover job opportunities. You can access all of this through our private Facebook group.
In this blog we will review the theory of the Air gaps in magnetic circuits. A magnetic circuit is where a magnetic flux is circulated or follow through a closed area or path. An air gap is a non-magnetic part of a magnetic circuits and it is usually connected magnetically in series with the rest of the circuit. This allows a substantial part of the magnetic flux flows through the gap.
As we are still in the middle of a pandemic, many post-secondary institutions have shifted their traditional in-class instruction and delivery of programs and courses online. Our programs have always been delivered online, and we have the resources and services to help support your success through your studies. Whether it’s looking for technical support or downloading your eCertificates, you may need to access various resources and services from time to time.
In this blog we will review the theory of the Current Divider circuits in a parallel circuit. In a parallel circuit, all the components have their terminals connected together sharing the same two end nodes. This results in different paths and branches for the current to flow or pass along. However, the currents can have different values through each component but the voltage remains the same across two end nodes.
As Covid-19 is brought under control, many people are anxious to get back to work. While some may be able to work from home, it is important that safety measures are in place for those who must physically return to their workplaces. The manufacturing industry must have measures in place to prevent the potential spread of the virus as technicians return to warehouses, factories, and other workplaces. Let us review a few new technologies and procedural changes employers can implement to ensu
In a 2018 study by Deloitte and the Manufacturing Institute it was predicted that by 2028 there would be in excess of two million unfilled positions in manufacturing—a deficit created by what is being called the “Manufacturing Skills Gap.” The changing landscape of the manufacturing industry, paired with an outdated repu
Since March, the GBCTechTraining team has seen a number of changes to our processes, due to the Covid-19 pandemic. We have had to rethink the ways that a number of our resources are delivered, including how students access their program materials and documents. Physical materials and documents can no longer be sent out due to the closure of GBC’s physical location and mail room—so we have had to take these materials fully digital! Here a
In theatre, being a Triple Threat means that you can sing, dance, and act—that you have all the skills necessary to take on any role and succeed at it. This term can be applied to manufacturing, as well, and refer to someone who has skills in multiple disciplines, able to take on work in many departments.
Here at GBCTechTraining, we take student support very seriously. This means keeping track of the questions both current and prospective students ask regularly, anticipate potential questions, and make answers and information accessible to all. However, there are always questions that we may not foresee, but would love to answer!
As we continue through the Covid-19 pandemic, many changes continue to affect how we at George Brown College are operating. While physical locations at the school remain closed, we are working hard to provide our students with uninterrupted access to their academic credentials. Towards this end, GBC has introduced the ability for students to download their official academic transcripts electronically, as Official eTranscripts.
In this blog we will explore Inductance; one of the major properties of an electrical circuit or an electronic device. Inductance is defined as a property of electrical circuit or a device that opposes a change in current. It is important to note that inductance does not oppose the current but rather opposes the change in current flowing within the circuit.
Here at GBCTechtraining, we are very proud of our graduates. Their stories inspire us, and we hope they will inspire you as well!

In electronics, filters serve a critical role in many common applications such as audio electronics, radio communications and power supplies. We use filters to block or pass a specific range of frequencies. The filters can be either passive or active. We usually divide filters into four main types, depending on which frequency components of the input signal they pass on to the output signal. The four types of filters are low-pass, high-pass, band-pass, and band-stop.
The COVID-19 pandemic and our government’s public health and societal response to it are having a dramatic effect on all of our lives, and the way we interact with each other as individuals, businesses and public institutions. George Brown College and our distance learning department have been challenged to adapt and adjust the delivery of our programs.
Students often think that once they gain technical knowledge, they are ready to go and get that career they've always wanted. They often overlook the soft skills, thinking that they're something that we're all naturally good at (or not).

Electromechanical technicians play a vital role in our economy as many industrial systems are built with electromechanical devices.
Almost every moving device is powered by an electro mechanical system. These systems are present in most electric motors, solenoids and mechatronics. From vehicle power windows and power seats to washers and dryers, many of the products we use in our everyday lives rely on these systems.
In this installment of the "Practicing Technician" series we will review the calculation required to determine the resistance of a given conductor. This often overlooked parameter can be important when trying to determine the appropriate wire diameter for a given application. It is also important to consider conductor resistance when examining application efficiency. Lower resistance means lower power dissipation by the conductor.
Two commonly misunderstood types of training are certificates and certifications. Both provide important value, but are quite different in terms of purpose, content, oversight and commitment required to complete them. Selecting the right training will ultimately increase your hire ability and/or value to your employer.
Most people use HMIs regularly in everyday life. For instance, when they’re adjusting the temperature controls in their vehicles or homes, they’re engaging a human-machine interface. In industrial applications, HMIs are often more complex interfaces capable of handling the volume and complexity of inputs and outputs necessary to operate industrial machinery or plant-wide operations.
In this installment of our "Practicing Technician" series, we will once again be working with a circuit reduction technique. This particular technique is quite useful for determining how changes in load conditions can impact on circuit performance. Until now, we have provided reduction techniques that are useful for fixed load circuit analysis. Thevenin's theorem can be used in cases where we want to see how load voltage, current and power are effected by changes in load resistance.
In the fourth part of our series on Tips For Practicing Technicians, we look at a simple technique that can be used to simplify circuit analysis when working with series and parallel RL circuits. One of the issues encountered by technicians who are working with parallel RL circuits is the need to work with values that are the reciprocals of the more commonly used standard units.
Augmented reality (AR) and virtual reality (VR) are two of the ways tech changes the way we look at the world. Whereas AR enhances our experience by superimposing digital images on our reality (think Pokémon Go), VR creates a completely different reality with a simulated environment. While both are typically used in technology for entertainment, they can also help improve industries such as manufacturing.
This is the third in our series of brief articles discussing important topics relevant to electronics and electromechanical technicians and technician students preparing for today’s workforce. In this series, we will be discussing some everyday skills and topics for practicing technicians, as well as some areas that have been identified as “difficult to understand” by our technician students while performing general circuit analysis.
Everybody knows that increased automation on the factory floor dealt a severe blow to manufacturing workers everywhere. Now, white collar jobs are also about to undergo quite a few shakeups as automation begins to take over offices, schools, hospitals and research labs everywhere.
Electromechanical switches are devices designed and used as additions for electrical circuits. They register over current, over-voltage, reverse power flow, and frequency. All of this is done in order to reduce the risk of major accidents or flashovers related to the electrical system within a structure or in machinery. Essentially, they work by tripping the circuit breaker when a fault is detected.
It's been a rough few years for the manufacturing industries, highlighted by the end of the first decade in the twenty first century where the most serious recession since the Great Depression affected most, if not all of the world’s economy. Most sectors seem to have rebounded, and the manufacturing industry is no exception.
The face of aviation is expected to change drastically over the next several decades. New regulations are driving the demand for electric and hybrid aircraft that produce fewer carbon emissions. Organizations like NASA and Airbus are leading the way to cleaner aviation by researching and designing green aircraft propulsion technologies.
The surprise result of the recent US election has highlighted the loss of manufacturing jobs like never before. Voters punished the status quo at the ballot box, at least partially because of their anger and powerlessness at big business outsourcing work to foreign countries. But the problem on the horizon is not so much outsourcing, downsizing, or imports as it is a fourth industrial revolution: the mass introduction of automation, which will replace low-wage workers with robots.
A recent technological breakthrough in the efficiency of the electric motor could mean that the average family’s grocery bill is about to drop – significantly. QM Power, a technology firm located in Kansas City, Missouri, recently broke the news to the world that it had developed an electric motor that promised to be at least 80% more efficient than Tesla’s (the man, not the automaker) induction electric motor.
One of the more remarkable consumer technologies to really take flight in the last few years are drones; but the one that is really turning heads is Parrot’s Oculus Rift compatible drone, Bebop.
