This course introduces single phase, electrical power definitions and calculations. Energy and power considerations are at the heart of determining electrical operating costs. A basic knowledge of the relationships between the power source and typical electrical lo Learn More>>
Overview This course is a refresher in basic network analysis of passive RLC circuits using discreet passive (R) resistor, (L) inductor and (C) capacitor components. The complete response for each of the 4 basic circuits has transient and steady state... Learn More>>
I wrote this course with the intention of removing the magic and mystique that surrounds the idea of three phase circuits. With that in mind, this course starts by reviewing single phase alternating current circuits including resistive,... Learn More>>
Circuit control in its simplest form, is the application and removal of power. This can also be expressed as turning a circuit on and off or opening and closing a circuit. Before you learn about the application of circuit control devices, you should know why circui Learn More>>
Reactance is the measure of the opposition to the flow of alternating current caused by the inductance and capacitance in a circuit rather than by resistance. Steady electric currents flowing along conductors in one direction undergo opposition called... Learn More>>
There are two basic methods of circuit protection. They are fuses and circuit breakers. There are many variations of fuses and circuit breakers. This course attempts to explain how and why fuses and circuit breakers work. There is some basic theory upon which these Learn More>>
Overview This 4-hour course covers the application of symmetrical components to unbalanced conditions on electric power systems. Unbalanced conditions occur during faulted conditions and can be very difficult to analyze using basic circuit analysis. Applying the Learn More>>
