The capacitor of figure 2.1 is initially charged to 20 V and the switch S is initially open. The switch is then closed at time t = 0. Sketch the discharging curve of the capacitor voltage after the switch is closed. 1) ii) Write down the equation of this discharging curve. How long will it take for the voltage to decay to 5 V?
