Question 2

A certain series resonant circuit has a bandwidth of 1000 Hz. If the existing coil is replaced with a coil of lower Q value (no change in resonant frequency), what will be the change in the bandwidth?

Question 3

An input voltage  is applied to a series combination of resistance and an inductance The resulting steady state current i(t) in ampere is
