MCQ
Identify the semiconductor devices whose characteristics are given below, in the order $(a),(b),(c),(d) $ 
  • A
    Solar cell, Light dependent resistance, Zener diode, simple diode
  • B
    Zener diode, Solar cell, simple diode, Light dependent resistance
  • ✓
    Simple diode, Zener diode, Solar cell, Light dependent resistance
  • D
    Zener diode, Simple diode, Light dependent resistance, Solar cell
✓

Answer

Correct option: C.
Simple diode, Zener diode, Solar cell, Light dependent resistance
c
Graph $(a)$ is for a simple diode.

Graph $(b)$ is showing the $V$ Break down used for zener diode.

Graph $(c)$ is for solar cell which shows cut-off voltage and open circuit current.

Graph $(d)$ shows the variation of resistance $h$ and hence current with intensity of light.
