INTRODUCTIONIn electrical engineering, we are often interested in communicating or transferring energy from one point to another. To do this requires an interconnection of electrical devices. Such interconnection is referred to as an electric circuit, and each component of the circuit is known as an element.

ELECTRIC CIRCUIT is an interconnection of electrical elements.Tuesday, June 09, 2015Engr. J.L. Tumbaga7
