Series LCR Circuit

When a capacitor is connected in series LR circuit, the alternating current flowing in the circuit

Show answer and solution

Answer: (a)

LR: $Z = \sqrt{R^2 + X_L^2}$ . With $C$ : $Z' = \sqrt{R^2 + (X_L - X_C)^2}$ .
$X_C$ partly cancels $X_L$ , so $Z' < Z$ (for $X_C < 2X_L$ , the usual case).
Smaller impedance, larger current: answer (a) increases.
