Question

1. Advantages of parallel circuits in domestic wiring?

2. Derive an expression for equivalent resistance for series and parallel combination?

Answer 1

Heya mate !!

following are the advantage of parallel circuits in domestic wiring :-

1. if one device gets affected or stop working then other devices not...they keep working continuously.
2.there are separate switch to on or off ..each electrical device.

2. In series = R= R1 +R2 + R3
where as in parallel :- 1/R = 1/R1 + 1/R2 + 1/R3
= R =(R1 + R2 + R3 )/ R1 × R2 ×R3
