Question

What will be the percentage increase in power across each circuit if the current is increased by
2%?
(A) 4%
(B) 4.4 %
(C) 4.04 %
(D) None of these

Answer 1

Answer:

Keeping all other parameters constant, if the current in the circuit is increased by 2%, the increase in power will be 4.04%

Explanation:

Power is proportional to I*I and hence new power will be (1.02*1.02)*Original Power
