For the given circuit, what is the minimum peak value of the output waveform if the input waveform is 10V square wave with switching time of 1 second? Assume that the input switches between +10V and -10V DC levels.

For the given circuit, what is the minimum peak value of the output waveform if the input waveform is 10V square wave with switching time of 1 second? Assume that the input switches between +10V and -10V DC levels. Correct Answer -20 V

For the positive half of the input, the diode is in the on state and hence acts as a short circuit and hence vo = 0 V. For the negative half cycle, the resistor receives voltage input both from the source and the capacitor which is charged during the positive half of the input. Hence, vo = -20 V.
