A step function voltage is applied to an RLC series circuit having R \(=2 \Omega, \mathrm{L}=1 \mathrm{H}\) and \(\mathrm{C}=1 \mathrm{~F}\). The transient current response of the circuit would be:
(a) overdamped
(b) critically damped
(c) underdamped
(d) over, under or critically damped depending upon the magnitude of the step voltage.
