A circuit draws 330 W from a 
line. The power factor is 0.6 and the current lags the voltage. The capacitance of a series capacitor that will result in a power factor of unity is equal to
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
Resistance of circuit,
Ist case Power factor, 
Since, current lags the voltage, thus the circuit contains resistance and inductance.
… (i)
IInd case Now 
[given]
Therefore, circuit is purely resistive, i.e. it contains only resistance. This is the condition of resonance in which
