Rectification and smoothing — practice question

(a(i))[1]

State the meaning of rectification when applied to an alternating voltage.

(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 for half-wave rectification of an alternating input voltage $V_{IN}$, giving an output voltage $V_{OUT}$ across the resistor $R$.

(b(ii))[1]

State the function of the capacitor $C$ in the circuit shown in Fig. 6.1.

(c)

In Fig. 6.1, the input voltage $V_{IN}$ is a square wave. Fig. 6.2 displays how $V_{IN}$ changes with time $t$.

(d(i))[2]

Show that the capacitance of $C$ has a value of $570\,\mu\text{F}$.

(d(ii))[3]

Determine the value of resistance $R$.
