In series LCR circuit, the plot of `I_("max")` versus `omega` is shown in figure. Find the bandwidth and mark in the figure.

Text Solution

Verified by Experts

As is know for theory, bandwidth = frequency range at which
`I = (1)/(sqrt2) I_(max) = 0.7 I_(max)`.
In Fig. band width, `Delta omega 1.2 - 0.4 rad//s`.
