Question 3 POST_UTME_KSU • 2023 • PHYSICS • objective

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

A. Z = \sqrt{R^2 + $ \omega L + \frac{1}{\omega C} $^2}

Correct Answer B. Z = \sqrt{R^2 + $ \omega L - \frac{1}{\omega C} $^2}

C. Z = \sqrt{R^2 + $ \omega L + \frac{1}{\omega C} $^2}

D. Z = \sqrt{R^2 + $ \omega L - \frac{1}{\omega C} $^2}

Correct Answer

Correct Option:

Z = \sqrt{R^2 + $ \omega L - \frac{1}{\omega C} $^2}
