In the following circuit, if the input wave form is as shown in the figure, what will be the wave form (i) across R in Fig. and (ii) across the diode in Fig. Assume that the diode is ideal.

Text Solution

Verified by Experts

(i) During the positive half of wave form, p-n junction is forward biased. Due to it we get output voltage across R. During negative half of waveform, p-n junction is reversed biased. No output across R.
(ii) During the positive half of waveform, p-n junction is reverse biased and during negative half of wavefrom, p-n junction is forward biased.
