Question 1

[Maximum number: 2]

Four diodes are used in a bridge rectifier circuit to produce rectification of a sinusoidal a.c. input voltage VIN V_{\text {IN }}.
Fig. 7.1 shows part of the circuit, but three of the diodes are missing.

The p.d. across the load resistor R is the output p.d. VOUT V_{\text {OUT }} of the bridge rectifier.

VIN V_{\text {IN }} has amplitude V0V_{0} and period T. Fig. 7.2 shows the variation with time t of VIN V_{\text {IN }}.

The power dissipated in the resistor is P.

On Fig. 7.4, sketch the variation of P with t between t=0 and t=2.0 T.
