Question: 14 the system shown in fig 15a is constructed so...

Question details

1-4. The system shown in Fig. 1-5(a) is constructed so that the capacitance of the plates has the time variation shown in Fig. P1-4. Sketch the 2tFig. P1-4. waveform of the variation of current in the circuit with time. On your sketch, superimpose the waveform of capacitance variation to show the relationship of the two variables. Plate Battery Plate Motor (constant speed) AL Fig. 1-5.A motor-driven capacitor produces a time-varying capaci- tance as shown in (b) such that the current from the battery is that shown in (c)
