How to Work Electrical Circuits?

This lecture focus to describe on How to Work Electrical Circuits? A simple electrical circuit contains four parts: a power source, a load, connectors and a switch. An electric circuit is a path in which electrons from a voltage or current source flow. The point where those electrons enter an electrical circuit is called the “source” of electrons. The point where the electrons leave an electrical circuit is called the “return” or “earth ground”.
