A) \[200\]
B) \[100\]
C) \[50\]
D) \[25\]
Correct Answer: B
Solution :
[b] Current gain \[=\frac{\Delta {{I}_{C}}}{\Delta {{I}_{B}}}\] when \[{{V}_{CE}}\] is constant. \[=\frac{2.5\times {{10}^{-3}}}{25\times {{10}^{-6}}}=0.1\times {{10}^{3}}=100\] \[[\Delta {{I}_{B}}=125\,\mu A-100\mu A=25\,\mu A\] \[\Delta {{I}_{C}}=7.5\,mA-5\,mA=2.5mA]\]You need to login to perform this action.
