Circuit Elements

“I’ve never seen electricity; that’s why I don’t pay for it.”

Steven Wright

Our study of electricity and power distribution would be incomplete without understanding certain circuit elements, such as resistors, inductors, capacitors, and transformers, and the way they behave, combine, and interact. Resistance, inductance, and capacitance are elements of impedance; they impede the flow of AC and/or DC. But they do it in different ways. Resistors convert electrical energy to heat energy, while inductors and capacitors store electrical energy. In the process, they each limit the free flow of AC and/or DC.

Resistance is ...
