Question 37 POST_UTME_OAU • 2018 • PHYSICS • objective

A circuit consists of a resistor $R$ and an inductor $L$ connected in series. The circuit is driven by a voltage source $V(t) = V_0 \cos$ \omega t $$. If the induc\tance is $L = 0.1 H$ and the resis\tance is $R = 10 \Omega$, calculate the impedance $Z$ of the circuit.

Correct Answer A. \sqrt{R^2 + \omega^2 L^2}

B. \sqrt{R^2 - \omega^2 L^2}

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

D. \sqrt{R^2 - \frac{1}{\omega^2 L^2}}

Correct Answer

Correct Option:

\sqrt{R^2 + \omega^2 L^2}
