The V-I characteristic of a diode is shown in the figure. The ratio of forward to reverse bias resistance is :

JEE Main 2017 (Online) 8th April Morning Slot Physics - Semiconductor Question 172 English

Multiple Choice Options

  • A 10
  • B 10−6
  • C 106
  • D 100

Step-by-Step Verified Solution

Forward bias resistance

R1 = ΔVΔI = 0.8−0.7(20−10)×10−3 = 10 Ω

Reverse bias resistance,

R2 = 101×10−6 = 107 Ω

∴ Ratio of resistance

= R1R2 = 10107 = 10−6
