Answer Options

Correct Answer A. \sqrt{R^2 + \( \omega L - \frac{1}{\omega C} \)^2}
B. \sqrt{R^2 - \( \omega L - \frac{1}{\omega C} \)^2}
C. \sqrt{\( \omega L - \frac{1}{\omega C} \)^2 - R^2}
D. \sqrt{\( \omega L + \frac{1}{\omega C} \)^2 - R^2}
Correct Answer
A
Correct Option:
\sqrt{R^2 + \( \omega L - \frac{1}{\omega C} \)^2}
