In a series LCR circuit, the frequencies at which the current amplitude is`(1)/(sqrt(2))`mes the current amplitude at resonance are` f_(1) and f_(2) (gt f_(1)).` Find the frequency bandwidth of resonance which is defined as `Deltaf=f_(2)-f_(1).` Express your answer in terms of R and L. Assume that resonance frequency `f_(0)gtgtDeltaf`
