A circuit consists of a resistor $R$, an inductor $L$, and a capacitor $C$ connected in series. If the impedance of the circuit is $Z = \sqrt{R^2 + \( \omega L - \frac{1}{\omega C} \)^2}$, find the phase angle $\phi$ of the circuit.

Answer Options

Correct Answer A. \phi = \arc\tan\left\( \frac{\omega L - \frac{1}{\omega C}}{R}\right \)
B. \phi = \arc\tan\left\( \frac{R}{\omega L - \frac{1}{\omega C}}\right \)
C. \phi = \arc\tan\left\( \frac{R}{\omega L + \frac{1}{\omega C}}\right \)
D. \phi = \arc\tan\left\( \frac{\omega L + \frac{1}{\omega C}}{R}\right \)
Correct Answer
A
Correct Option:
\phi = \arc\tan\left\( \frac{\omega L - \frac{1}{\omega C}}{R}\right \)
