Fig. 4 shows the charging and discharging circuit of a polarized capacitor. a) Draw the charging and discharging circuits in separate diagrams. [4 marks] b) Calculate the time constant of the charging and discharging modes. [5 marks] c) If switch S, is closed and Sy is kept open at time t=0, explain the operation [8 marks] of the circuit with the aid of diagrams and voltage/current waveforms. d) If switch S, is opened and S2 is closed at time t=57, explain the operation of [8 marks] the circuit with the aid of diagrams and voltage/current waveforms.
