21.2.2—The use of a single diode for the half-wave rectification of an alternating question 1

[Maximum number: 1]

The output potential difference (p.d.) of an alternating power supply is represented by

V=320sin⁡(100πt)V=320 \sin (100 \pi t)

where V is the p.d. in volts and t is the time in seconds.

The power supply is connected to resistor R and a diode in the circuit shown in Fig. 10.1.
