Previous tutorials have shown the properties and characteristics of simple resistor-only and inductor-only AC circuits. We will now investigate the effects of combining the two components together.

A special frequency determined by the values of the resistance, capacitance and inductance refers to the resonance in AC circuits. The resonant frequency point occurs where the inductive reactance of ...

Inductance is the link between electric circuits and magnetic fields. Voltage and current sine waves are in-phase when they peak and cross the zero axis at the same time. However, this rarely happens ...

Any electrical motor, from an idealized viewpoint, consists of two sets of magnets—one set stationary, one set free to move—placed in special geometric relation to one another. For most practical ...

It's essential to understand how power and energy calculations relate, especially with the increased importance of energy efficiency. Calculations of power and energy are relatively straightforward ...

Power relays are specifically designed to handle either AC or DC. It’s important to know the fundamental differences between them before building them into a system. Introduction to AC and DC Power ...
