Please answer this question from electricity chapter

Answer 1

Answer:0.008 KWH

Explanation:Energy = Power × Time

or E=P×t .......(1)

First of all we should calculate power P by using the current of 4A and voltage of 12 V.

Now, P=V×I

So, P=12×4

or, Power, P=48 watts

=481000 kilowatts

Thus, Power, P=0.048kW

And, Time, t=10 minutes

=1060 hours

=16 hours

Now, putting P=0.048kW and, t=16 hours in equation (1), we get:

E=0.048×16

=0.008kWh

Thus, the energy transferred is 0.008 kilowatt-hour.
