Semiconductor Electronics Materials Devices And Simple Circuits Ques 89
89. The transfer ratio $\beta$ of a transistor is 50 . The input resistance of the transistor when used in the common emitter configuration is $1 k \Omega$. The peak value of the collector A.C. current for an A.C. input voltage of $0.01 V$ peak is
[1998]
(a) $100 \mu A$
(b) $0.01 mA$
(c) $0.25 mA$
(d) $500 \mu A$
Show Answer
Answer:
Correct Answer: 89.(d)
Solution:
- (d) $i_c=\beta \cdot \frac{V_s}{R _{\text{in }}}=50 \times \frac{0.01}{1000}=500 \times 10^{-6} A$
$=500 \mu A$
