Answer :

WIRING METHODS
 A circuit is a path along which the electric current flows from the negative Side of the power source to the positive side. There are three types of electrical circuit.
(i) Series circuit
(ii) Parallel circuit
(iii) Combination of series and parallel circuit.

SERIES CIRCUIT
 The series circuit provides a single, continuous path through which current flows. In this the devices are connected one after another and the current flows through them until it returns to the power source. The circuit is shown in fig. Hence, even when one device breaks down the remaining devices will not operate because the circuit is broken.

PARALLEL CIRCUIT
 In parallel circuit the devices are connected side by side so that, current flows in a number of parallel path. The parallel circuit is shown in fig. In this type of circuit each device is connected across the power source so that even if one device breaks down, the other devices continue to operate. Hence this type of circuit is used in home wiring.
