Identify the semiconductor devices whose characteristics are given below, in the order (a), (b), (c), (d)
Open in App
Solution
The correct option is A Simple diode, Zener diode, Solar cell, Light dependent resistance
Zener diode:
It can operate continuously without being damaged in the region of reverse biased
but
1) It acts as a voltage regulator
2) In forward biasing it acts as an ordinary diode.
Solar cells:
It is based on the photoelectric effect. It converts solar energy into electrical energy.
But:
One of the semiconductor regions is made so thin that the light incident on it reaches the PN junction and get absorbed.
(a) represents simple diode.
(b) represents zener diode
(c) solar cell
(d) light dependent resistance.
