A) 6
B) 20
C) 16
D) 12.5
Correct Answer: D
Solution :
The output resistance is given by \[R=\frac{{{V}_{c}}}{{{I}_{c}}}\] Given, \[{{V}_{c}}=0.5\,V,\,{{I}_{c}}=0.04\,mA\] \[=0.04\times {{10}^{-3}}A\] \[\therefore \] \[R=\frac{0.5}{0.04\times {{10}^{-3}}}\] \[=12500\,\,\Omega =12.5\,\,k\Omega \]You need to login to perform this action.
