Question 163: Semiconductors and Logic Gates

Question

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

Accepted Answer

Forward bias resistance
R
1
= $${{\Delta V} \over {\Delta I}}$$ = $${{0.8 - 0.7} \over {\left( {20 - 10} ight) 	imes {{10}^{ - 3}}}}$$ = 10 $$\Omega $$
Reverse bias resistance,
R
2
= $${{10} \over {1 	imes {{10}^{ - 6}}}}$$ = 10
7
$$\Omega $$
$$	herefore\,\,\,$$ Ratio of resistance
=  $${{{R_1}} \over {{R_2}}}$$ = $${{10} \over {{{10}^7}}}$$ = 10
