Question

The self inductance of the motor of an electric fan is 10 H.
In order to impart maximum power at 50 Hz, it should be
connected to a capacitance of
(a) 8μF (b) 4μmF (c) 2μF (d) 1μF

Answer 1

Answer:

I think option d is right ans

Answer 2

Explanation:

Lw=1/cw

w=omega

cw=1/Lw

c=1/Lw^2

c=capacitence

L=self inductance
