In a series L-C-R circuit, resistance R=10 and the impedance Z=10 . The phase difference between the current and the voltage is

Step-by-step solution

Impedance, aligned Z & = R^2+ (X_L-X_C )^2 10 & = (10)^2+ (X_L-X_C )^2 100 & =100+ (X_L-X_C )^2 X_L-X_C & =0....(i) aligned Let is the phase difference between current and voltage aligned & & & = X_L-X_C R & & & = 0 R & & & =0 aligned [from Eq. (i)]
