A) 10-1 :1
B) 10-2:1
C) 10-3 :1
D) 10-2 : 1
Correct Answer: D
Solution :
Resistance of forward bias p-n junction \[{{R}_{f}}={{10}^{2}}\Omega \] ...(i) Resistance of reverse bias p-n junction \[{{R}_{r}}={{10}^{6}}\Omega \] ...(ii) So, from Eqs. (i) and (ii) \[\frac{{{R}_{f}}}{{{R}_{r}}}=\frac{{{10}^{2}}}{{{10}^{6}}}=\frac{{{10}^{-4}}}{1}\]
