A step voltage is applied to an under-damped series RLC circuit with variable R. Which of the following statements correctly describe the behaviour of the circuit?
(1). If R is increased, the steady state voltage across C will be reduced
(2). If R is increased, the frequency of transient oscillation across C will be reduced.
(3). If R is reduced, the transient oscillation will die down faster.
(4). If R is reduced to zero, the peak amplitude of the voltage across C will be double the input step voltage.
