The Central Concept: Closed Circuit

Primary objective of this lecture is to present on Central Concept of Closed Circuit. Closed circuit is an electric circuit through which current can flow in an uninterrupted path. Compare open circuit. A television system in which the signal is usually sent by cable to a limited number of receivers. Electric current is measured in amps (A) using an ammeter connected in series in the circuit.
