C P3: In the figure, R1 = 10 kN, R2 = 15 kN, C = 0.4 pF, and the ideal battery has emf E= 20 V. First, the switch is closed a long time so that the steady state is reached (i.e. capacitor is fully charged). Then the switch is opened at time t =0. For resistor 2 and time t = 4 ms, what are the [Total 7 marks) (a) current? [2.5 marks] (b) rate at which the current is changing ? 8 dt R W dP [3 marks] (c) rate of change of thermal power dissipation ? [1.5 marks] dc
