Electric current is caused by moving electric charges. The effects of charge and electric fields can be investigated by looking at the forces they exert on conductors and insulators. Simple circuits - ...

A diode is a tiny component with a powerful job—controlling the direction of electrical current. This video explains how ...

The current-mode or peak-current-regulating switching converter is a familiar, almost dominant, power supply circuit consisting of few parts and is usually designed with “cookbook” procedures from PWM ...

Ordinary power supply design includes current limiting as a protection feature. In product design, this is usually sufficient in that the engineer decides the loads on the supply by design. However, ...

The difference between static discharge and continuous current is explained. Introduction to Electric Current: The difference between static discharge and continuous current is explained. Sources of ...

Inductors are simple coils of wire, but they play a powerful role in electronics. This video explains how inductors store ...

To make something work using electricity there needs to be an electrical circuit; a circuit is a complete loop that electricity can move around. Electricity moves from the power source (the battery or ...
