Electronic Devices Question 191

Question: In a triode amplifier, $μ = 25, r_{p} = 40$ kilo ohm and load resistance $R_{L} = 10$ kilo ohm. If the input signal voltage is 0.5 volt, then output signal voltage will be

[RPMT 1995]

Options:

A) 1.25 volt

B) 5 volt

C) 2.5 volt

D) 10 volt

Show Answer

Answer:

Correct Answer: C

Solution:

Voltage gain $= \frac{V_{out}}{V_{in}} = \frac{μ}{1 + \frac{r_{p}}{R_{L}}}$
$\Rightarrow \frac{V_{out}}{0.5} = \frac{25}{1 + \frac{40 \times 10^{3}}{10 \times 10^{3}}}$
$\Rightarrow V_{out} = 2.5 V$ .
