Question

An inductance L having a resistance R is connected to an alternating source of angular frequency $\omega$. The quality factor (Q) of the circuit is

• A. ${\left(\frac{\omega L}{R}\right)}^2$
• B. ${\left(\frac{R}{\omega L}\right)}^{1/2}$
• C. $\frac{\omega L}{R}$
• D. $\frac{R}{\omega L}$

Answer 1

Answer: (C)

$\frac{\omega L}{R}$

$Q=\frac{w_0}{\Delta w}=\frac{w_{0}L}{R}$
