Document Summary

An electric circuit is a way through which electric current flows. An electric circuit can likewise be a closed path (in which the finishes are joined), in this manner making it a loop. The progression of electric flow is conceivable due to the closed circuit. An electric circuit can likewise be an open circuit in which the progression of electrons is cut, in light of the fact that the circuit is broken. Electric flow doesn"t pass through in an open circuit. Being familiar with the fundamental parts of an electric circuit is significant. A basic electric circuit contains a source, a switch, a load, and a conductor. Cell: it is used as a source to supply electric current. It is basically a light bulb, which glows when the circuit is turned on. Conductors: copper wires are used as conductors with no insulation.
