Rectification and smoothing — practice question
Alternating current (a.c.) is changed to direct current (d.c.) by means of a full-wave rectification circuit. Figure 7.1 shows one section of this circuit diagram.
(a(i))[1]
Finish the circuit in Fig. 7.1 by adding the missing components into the gaps.
(a(ii))[1]
On Fig. 7.1, add a $+$ to show the positive output terminal of the rectifier.
(b(i))[2]
Determine the equation for $V$ in terms of $t$, where $V$ is in volts and $t$ is in seconds.
(b(ii))[2]
A $12\Omega$ resistor is connected to the supply. Calculate the mean power dissipated in the resistor.
