Question

If in a p-n junction diode, a square input signal of 10 V is applied as shown.

Then, the output signal across RL will be

Answer 1

Correct Option (d)

Explanation:

During - ve cycle, diode will not allow the signal to

For Vi < 0, the diode is reverse biased and hence offer infinite resistance, so circuit would be like as shown in Fig (ii) and Vo = 0

For Vi>0, the diode is forward biased and circuit would be as shown in Fig. (iii) and Vo = Vi.

Hence, the option (d) is correct.
