Question

Assertion: Parallel combination is preferred over series combination in a domestic circuit. Reason: The potential difference remains the same in parallel combination.l

Answer 1

reason is not the correct explanation of assertion...

hope it helps

please give thanks

Answer 2

Parellel combination is preferred over series combination because of the following reasons:-
1) In parallel combination each appliance gets the full voltage.
2) If one appliance is switched on/of others are not affected.
3) The parallel circuit divide the current through the appliances. Each appliance gets proper current depending on its resistance.
4) In a parallel combination it is very easy to connect or disconnect a new appliance without affecting the working of other appliances.

But in a parallel combination the potential difference remains the same.
Therefore, Both A and R are true but R is not the correct explanation of A
