The capacitor C shown in figure 4 is initially uncharged and the switch S is opened.
(i) Use Laplace transform to derive an expression for the current i (t) that flows in the circuit immediately after closing the switch S.
(ii) Determine whether the circuit is critically damped, under-damped or over-damped. All the relevant formulae and equations used in the solutions should be clearly stated. Use the most appropriate theories and equations used in the solutions should be clearly stated.
The question belongs to Electrical Engineering and it discusses about using Laplace transform to derive an expression for the flow of current in a circuit.
