Electronic Devices Question 193

Question: For a triode rp=10 kilo ohm and gm=3 milli mho. If the load resistance is double of plate resistance, then the value of voltage gain will be

[RPMT 1994]

Options:

A) 10

B) 20

C) 15

D) 30

Show Answer

Answer:

Correct Answer: B

Solution:

Voltage gain AV=μ1+rpRL and μ=rp×gm

μ=10×103×3×103=30

Av=μ1+rp2rp=23μ=23×30=20.
