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 capacitor. Then what is the value of capacitance?
Given in the question :
Inductance = 10 H
Frequency of fan = 50 Hz
We know Resonance is the condition in which maximum power is achieved in an LR circuit.
Thus, for maximum power in LR circuit : XL = XC
