A component is absent from the circuit in Fig. 5.1. Complete Fig. 5.1 by inserting the circuit symbol for the missing component in the correct position.
A capacitor $C$ is included in the circuit of Fig. 5.1. State the effect on $V_{\text{OUT}}$ when the capacitor is added to the circuit.
Fig. 5.2 plots $V_{\text{IN}}$ against time $t$.
Determine the frequency corresponding to $V_{\text{IN}}$.
Show that the time constant $\tau$ for discharge of the capacitor through the resistor is $0.038\,\text{s}$.
Calculate the capacitance of $C$ and include a unit in your answer.
The circuit in Fig. 5.1 is changed so that it gives full-wave rectification of an input voltage. Suggest, with a reason, how $V_{\text{OUT}}$ now changes with time when $V_{\text{IN}}$ is as shown in Fig. 5.2.
Determine the frequency of $V_{\text{IN}}$.
Show that the time constant $\tau$ for discharge of the capacitor through the resistor is $0.038\,\text{s}$.
Calculate the capacitance of $C$ and state a unit in your answer.
