Question

If resonant frequency of a R-L-C circuit is ω0 and bandwidth is A ω, then which of the following quantity is regarded as a measure of the sharpness of resonance? (A) (ω0/Δ ω) (B) (ω0/2 Δ ω) (C) (2 ω0/Δ ω) (D) (Δ ω/2 ω0)

The quantity (ω0 / 2 Δ ω) is regarded as measure of the sharpness of resonance. The smaller the Δ ω, the sharper is the resonance.

Q. If resonant frequency of a $R - L - C$ circuit is $ω_{0}$ and bandwidth is $A ω$ , then which of the following quantity is regarded as a measure of the sharpness of resonance?

$\frac{ω _{0}}{Δ ω}$

$\frac{ω _{0}}{2Δ ω}$

$\frac{2 ω _{0}}{Δ ω}$

$\frac{Δ ω}{2 ω _{0}}$

The quantity $(ω_{0} /2Δ ω)$ is regarded as measure of the sharpness of resonance. The smaller the $Δ ω$ , the sharper is the resonance.
