State the meaning of rectification.
State the name of the type of rectification given by a bridge rectifier circuit.
Complete the circuit in Fig. 6.1 by drawing the three absent diodes inside the dashed circles.
The input voltage changes with time $t$ according to the equation $V_{\mathrm{IN}} = 34\sin 18t$, where $V_{\mathrm{IN}}$ is in V and $t$ is in s. Show that the period of the input voltage is $0.35\,\text{s}$.
Calculate the root-mean-square (r.m.s.) input voltage.
On Fig. 6.2, sketch how $V_{\mathrm{OUT}}$ varies with $t$ from $t=0$ to $t=0.35\,\text{s}$.
The resistance of resistor $R$ is $56\,\text{k}\Omega$. A capacitor with capacitance $12\,\mu\text{F}$ is added to the circuit of Fig. 6.1 to smooth the output voltage. On Fig. 6.1, draw the capacitor connected correctly into the circuit.
Calculate the time constant of the smoothing circuit.
During each discharge cycle, the capacitor spends $0.14\,\text{s}$ discharging. Determine the minimum value of the smoothed output voltage.
