A) \[10\,\,k\Omega \]
B) \[20\,\,k\Omega \]
C) \[5\,\,k\Omega \]
D) \[2.5\,\,k\Omega \]
Correct Answer: A
Solution :
Here\[\Delta {{V}_{c}}=0.5\,\,volt\] \[\Delta {{I}_{c}}=0.05\,\,mA=0.05\times {{10}^{-3}}A\] Output resistance is given by \[{{R}_{out}}=\frac{\Delta {{V}_{c}}}{\Delta {{I}_{c}}}\] \[=\frac{0.5}{0.05kt{{10}^{-3}}}={{10}^{4}}\Omega \] \[=10k\,\,\Omega \]You need to login to perform this action.
