Q. 22

# The gain factor o …(i)

where A is the voltage gain, μ is the amplification factor, RL is the load resistance and rp is the plate resistance

Given:

A1=10, Rl1 = 4kΩ

A2=12, Rl2 = 8kΩ

Putting these two values in equation (i)  We get a linear equation in 2 variables (rp and μ)  …(ii)

We will get another equation by substituting the values of A2 and Rl2 is equation (i)   … (iii)

Solving (ii) and (iii) to find the values amplification factor and the plate resistance. & From (ii) …(iv)

Substituting (iv) in (iii)   Using μ =15, the value of rp is 2000Ω or 2 kΩ
