Electronic Devices Question 216

Question: The transconductance of a triode amplifier is 2.5 mili mho having plate resistance of 20 KW, amplification 10. Find the load resistance

[RPMT 2001]

Options:

A) 5 kW

B) 25 kW

C) 20 kW

D) 50 kW

Show Answer

Answer:

Correct Answer: A

Solution:

Voltage amplification $A_{v} = \frac{μ}{1 + \frac{r_{p}}{R_{L}}} = \frac{r_{p} \times g_{m} \times R_{L}}{R_{L} + r_{p}}$
$\Rightarrow 10 = \frac{20 \times 10^{3} \times 2.5 \times 10^{- 3} \times R_{L}}{(R_{L} + 20 \times 10^{3})}$
$\Rightarrow R_{L} = 5 k Ω$ .
