A circuit consists of a resistor $R$, an inductor $L$, and a capacitor $C$ connected in series. If the circuit is driven by an alternating voltage source of frequency $f$, find the impedance $Z$ of the circuit.

Answer Options

Correct Answer A. Z = \sqrt{R^2 + \( X_L - X_C \)^2}
B. Z = \sqrt{R^2 + \( X_L + X_C \)^2}
C. Z = \sqrt{R^2 - \( X_L - X_C \)^2}
D. Z = \sqrt{R^2 - \( X_L + X_C \)^2}
Correct Answer
A
Correct Option:
Z = \sqrt{R^2 + \( X_L - X_C \)^2}
