(a(i))[1]
State what rectification of an alternating voltage means.
(a(ii))[2]
State how half-wave rectification differs from full-wave rectification.
(b(i))[2]
Complete Fig. 6.1 so that it shows a circuit giving half-wave rectification of an alternating input voltage $V_{IN}$ and producing output voltage $V_{OUT}$ across the resistor $R$.
(b(ii))[1]
State the function of the capacitor $C$ in the circuit of Fig. 6.1.
(c)
The input voltage $V_{IN}$ in Fig. 6.1 is a square wave. Fig. 6.2 shows how $V_{IN}$ changes with time $t$.
(c(i))[2]
Show that the capacitance of $C$ is $570\,\mu\text{F}$, given that the greatest energy stored in the capacitor is $0.041\,\text{J}$.
(c(ii))[3]
Determine the value of the resistance $R$.
