(c) The circuit in Figure Q2 (c) is switched on when $t = 0s$. Given that the voltage source, $V_s = 9u(t)$ and the circuit consists of 2Ω resistor, R and 2µF capacitor, C. If the initial voltage, V(0) is 4V.
(i) Draw the equivalent circuit in Laplace domain. [2 marks]
(ii) Determine the current, i(t) flowing in the circuit. [5 marks]
