Question:

A student has designed a full-wave rectifier circuit.

The output voltage for this circuit is taken across a resistor of resistance 120 Ω. The variation of the output voltage with time is shown.

A capacitor is now connected across the resistor. The graph shows the new variation of the output voltage with time.


a. Explain the variation of the output variation between points:

i. AB

ii. BC.

b. Use the second graph to determine the value of the capacitance C.
