A) \[{{10}^{-1}}:1\]
B) \[{{10}^{-2}}:1\]
C) \[{{10}^{-3}}:1\]
D) \[{{10}^{-4}}:1\]
Correct Answer: D
Solution :
Appears resistance ofp-n junction in forward biased\[{{R}_{f}}={{10}^{2}}\Omega .\] Appears resistance ofp-n junction in reverse bias \[{{R}_{r}}-{{10}^{6}}\Omega \] \[\frac{{{R}_{f}}}{{{R}_{r}}}=\frac{{{10}^{2}}}{{{10}^{6}}}={{10}^{-4}}\] \[{{R}_{f}}:{{R}_{r}}={{10}^{-4}}:1\]
