Semiconducting Devices Question 287

Question: Plate resistance of two triode valves is 2 KW and 4 KW, amplification factor of each of the valves is 40. The ratio of voltage amplification, when used with 4 KW load resistance, will be

[RPET 1998]

Options:

A) 10

B) $\frac{4}{3}$

C) $\frac{3}{4}$

D) $\frac{16}{3}$

Show Answer

Answer:

Correct Answer: C

Solution:

Voltage amplification $A_{V} = \frac{μ}{1 + \frac{r_{p}}{R_{L}}} = \frac{μ R_{L}}{R_{L} + r_{p}}$
$\Rightarrow \frac{A_{1}}{A_{2}} = \frac{2 + 4}{4 + 4} = \frac{3}{4}$ .
