The output of the given circuit in figure

Question

Professor PC Thomas Classes · Answer

(c) : During positive half cycle of input ac voltage, the $p-n$ junction is forward biased. The resistance of $p-n$ junction is low. The current in the circuit is maximum. In this situation, a maximum potential difference will appear across resistance connected in series of the given circuit. Due to it, there is no output voltage across $p-n$ junction. During the negative half-cycle of input ac voltage, the $p-n$ junction is reverse biased. The resistance of $p-n$ junction becomes high which will be more than resistance in series. Due to it, there will be voltage across $p-n$ junction with negative cycle in output.
