(a(i))[1]
State the meaning of rectification.
(a(ii))[1]
State the kind of rectification produced by the circuit in Fig. 5.1.
(b(i))[1]
On Fig. 5.1, mark terminals $P$ and $Q$ with the correct symbols to show the polarity of the output voltage $V_{\text{OUT}}$.
(b(ii))[3]
The change of $V_{\text{IN}}$ with time $t$ is given by the equation $V_{\text{IN}} = 6.0\sin 25\pi t$. The size of the output voltage $V_{\text{OUT}}$ varies with $t$ as shown in Fig. 5.2. On Fig. 5.2, label both of the axes using the correct scales.
(c(i))[1]
On Fig. 5.1, add the circuit symbol for a capacitor so that it is connected correctly in the circuit.
(c(ii))[2]
On Fig. 5.2, sketch how the smoothed output voltage varies with $t$.
(c(iii))[3]
Calculate the capacitance $C$ for the capacitor.
