parameters are to be found with the help of a sine wave gener-
ator and oscilloscope. Suggest a suitable experimental proce-
dure and explain how the values may be calculated from the
observations.
31.A series RLCcircuit with zero damping (i.e., with R 0) is
driven by a sinusoidal voltage source of unit amplitude. The
angular frequency of the source coincides with the value of
ω

of the circuit. Show that the zero-state response for capacitor
voltage in this case is 0.5 sin
