Overview - AC power systems operate at a nominal frequency. In the United States, this is 60 Hertz. In other parts of the world 50 Hertz...

What are Transients? - Transients describe the behavior of a circuit before it reaches a steady-state condition. This means that some new...

Basics - Heat transfer isn't what comes to most people's mind when they hear "electrical engineering", but for power systems engineers...

Kirchoff's Laws are statements about the nature of current and voltage. Unlike Ohm's Law, which describes the behavior of devices in a...

The dominant form of power generation, transmission, and distribution in the United States is via three-phase. Three-phase power uses...

At its most basic, power is the product of a current and a voltage at any point in time. In other words: Pn = Vn In Where: Pn is the...

Ohm's Law is the most important equation in all of electrical engineering. It is simple, used all the time, and underpins the physics of...
