Question

A battery of 10V carries 20000C of charge through a resistance of 20 ohm. The work done in 110 seconds is?

Answer 1

Answer:

Explanation:

Power= work done/ time

Power (P)= (voltage)^2/ resistance

So equating above two equations

V^2/R= W/t

W= V^2 × t/ R

= 100× 110/20

=11000/20

=550 J

Thanks.

Answer 2

550 J is the answer... Use the formula work done=V2/r and multiply the final answer by time

As work done= power*time
