A) 8 kW
B) 4 kW
C) 2 kW
D) 8 kW
Correct Answer: D
Solution :
\[{{i}_{p}}=\,[0.125\,{{V}_{p}}-7.5]\times {{10}^{-3}}\,amp\] Differentiating this equation w.r.t. Vp \[\frac{\Delta {{i}_{p}}}{\Delta {{V}_{p}}}=\,0.125\times {{10}^{-3}}\] or \[\frac{1}{{{r}_{p}}}=0.125\,\times {{10}^{-3}}\]Þ \[{{r}_{p}}\,=8\,k\Omega \]You need to login to perform this action.
