The potential differences across the resistance, capacitance and inductance are 80 V ,40 V and 100 V respectively in an L-C-R circuit. The power factor of this circuit is [NEET 2016]

Question

Accepted Answer

Correct answer: C. (c) Power factor of the L-C-R circuit = cos = RZ = IR IZ= 80I (X_L-X_C)^2+R^2 = 80 (IX_L-IX_C)^2+ ( IR )^2 = 80 (100-40 )^2+ (80 )^2=0.8
