A bridge rectifier contains four diodes. The output of the rectifier is connected to a resistor R, as shown in Fig. 10.1. bridge rectifier output resistor R input Fig. 10.1 The variation with time t of the input e.m.f. E to the rectifier is given by the expression E = 15 cos(210t ) where t is measured in seconds and E in volts. The variation with time t of the potential difference V across resistor R is shown in Fig. 10.2. V 0 t1 t2 time t Fig. 10.2 Determine:
