A) 100 mA
B) 0.01 mA
C) 0.25 mA
D) 500 mA
Correct Answer: D
Solution :
b = 50, Ri = 1000 W, Vi = 0.01V \[\beta =\frac{{{i}_{c}}}{{{i}_{b}}}\] and \[{{i}_{b}}=\frac{{{V}_{i}}}{{{R}_{i}}}=\frac{0.01}{{{10}^{3}}}={{10}^{-5}}A\] Hence \[{{i}_{c}}=50\times {{10}^{-5}}A=500\,\mu A\].You need to login to perform this action.
