Question

in household electric circuit different appliances are connected in parallel to one another give two reason and electrician put a fuse of ratings 5 year in the that part of domestic electric circuit in which an electrical heater of ratings 1.5 kilowatt 220 volt is operating what is likely to happen in the case and why what changed if any needs to made

Answer 1

Reasons : (1) Each appliance will be at the same potential i.e., voltage. 

(2) If one of the appliances fail, the others will still keep working. Rating of fuse = 5 A, 

V = 220 V , 

P = 1.5 kW = 1500 W 

Current in the circuit 

I = P/V = 1500/220 = 6.8 A 

The current in the circuit is more than the rating of the fuse. Therefore, the fuse will blow off. A fuse of rating of about 10 A should be put in the circuit.

Answer 2

The two reasons for arranging the circuit in parallel are:
i) if any of the appliance get damaged then all other should not
ii) it decreases the equivalent resistance……………………
In the case when a fuse with rating 5 ampere is passing the current of amount 6.81 ampere( by applying formula with given vales) it will be overload and the circuit will break.
In this type of case either the fuse should be replaced with one of the high capacity or the electricity should be consumed less.
