This video shows how the linkage of a H Frame Square D Breaker causes the switch contacts to open when the bi-metallic strip activates the trip unit when heated with a heat gun.

Demonstration of how to identify 9-lead motor wires using 24V AC an Ohmmeter and Voltmeter.

A short explanation of how a circuit breaker operates

This is a short demonstration video showing how conductors can be damaged by short circuits and fault current.

This video explains the process of solving for total inductance of series and parallel inductance. Finding total inductive reactance of a series or parallel circuit containing only inductors. Solving for circuits containing one or more inductors when their fields become interactive cumulatively or deferentially.

This video defines inductance and self-inductance. It defines Lenz's Law and how it applies to inductors. The factors that affect inductance. The relationships between voltage and current in DC inductive circuits. DC Circuit time constants and how they are associated with Euler's number.

This video is to help explain the starting sequence of a synchronous AC three phase motor. This example uses a motor shaft mounted DC Exciter generator with, a control circuit using a Polarized Field Frequency Relay, and Out of Step Relay. These relays help control the application of the DC Excitation when the motor approaches and runs at synchronous speed.

This video explains inductive reactance in an AC circuit, how to use reactance as a value in Ohm's law, how a phase shift is created in an AC circuit and the creation of VARs
