Semiconducting Devices Question 294
Question: The amplification factor of a triode is 18 and its plate resistance is 8 x 103W. A load resistance of 104W is connected in the plate circuit. The voltage gain will be
[RPMT 2002]
Options:
A) 30
B) 20
C) 10
D) 1
Show Answer
Answer:
Correct Answer: C
Solution:
Voltage gain $ A _{V}=\frac{\mu }{1+\frac{r _{p}}{R _{L}}}=\frac{18}{1+\frac{8\times 10^{3}}{10^{4}}}=10 $ .
