Semiconductor Electronics Materials Devices and Simple Circuits - Result Question 7

7. If in a p-n junction, a square input signal of $10 V$ is applied as shown, then the output across $R_L$ will be

[2015] (a)

(c)

(b)

Show Answer

Answer:

Correct Answer: 7. (c)

Solution:

  1. (c) Here P-N junction diode rectifies half of the ac wave i.e., acts as half wave rectifier. During + ve half cycle

Diode $arrow$ forward biased output across will be

During -ve half cycle Diode $arrow$ reverse biased output will not obtained.
