A) 67
B) 75
C) 100
D) 50
Correct Answer: C
Solution :
AC current gain \[\beta \] is defined as the ratio of the collector to the base current at constant collector voltage, \[\beta =\left( \frac{\Delta {{i}_{C}}}{\Delta {{i}_{B}}} \right){{V}_{c}}\] Given \[\Delta {{i}_{C}}=10\,mA-5mA=5mA\] \[\Delta {{i}_{B}}=150\,\mu A-100\mu A=50\,\mu A\] \[\therefore \] \[\beta =\frac{5}{50\times {{10}^{-3}}}=100\]You need to login to perform this action.
