Physics 9702: CAPACITANCE Topical Past Paper Questions

A capacitor of capacitance $ 47\ \mu F $, a cell of electromotive force (e.m.f.) $ 1.50 V $ and a resistor R are connected into the circuit of Figure 6.1. Figure 6.1 The two-way switch S alternates between terminals X and Y with a frequency of 0.20 Hz, as shown in the variation o…

Fig. 6.1 shows part of a bridge rectifier circuit that can be used for rectification of an alternating input voltage $ V_{IN} $. Fig. 6.1 The circuit contains four diodes, one of which is shown. The rectified output voltage $ V_{OUT} $ is applied across load resistor R. (a) (i) S…

(a) (i) State what is meant by rectification of an alternating voltage. (ii) State the difference between half-wave rectification and full-wave rectification. (b) (i) Complete Fig. 6.1 to show a circuit that produces half-wave rectification of an alternating input voltage $ V_{IN…
