Question

In a triode amplifier, $\mu = 25,r_{p} = 40$ 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.

Answer 1

Solution

Voltage gain

$= \frac{V_{\text{out}}}{V_{\text{in}}} = \frac{\mu}{1 + \frac{r_{p}}{R_{L}}} \Rightarrow \frac{V_{\text{out}}}{0.5} = \frac{25}{1 + \frac{40 \times 10^{3}}{10 \times 10^{3}}}$

$\Rightarrow V_{\text{out}} = 2.5V$ .
