Question

A series LCR circuit driven by 300 V at a frequency of 50 Hz contains a resistance R = 3 kΩ, an inductor of inductive reactance X_L = 250 πΩ and an unknown capacitor. The value of capacitance to maximize the average power should be : (Take π² = 10)

(1) 4 µF

(2) 25 µF

(3) 400 µF

(4) 40  µF

Answer 1

Correct Option is (1) 4 µF

For maximum average power
