Calculate the amplification factor of a triode valve that has plate resistance of 2 kΩ and transconductance of 2 millimho.

Open in App

Solution

Given:
Plate resistance, $r_{p} = 2 kΩ$

Transconductance of plate, $g_{m} = 2 mili mho = 2 \times 10^{- 3} mho$

Therefore, the amplification factor is given as:
$μ = r_{P} \times g_{m} μ = 2 \times 10^{3} \times 2 \times 10^{- 3} = 4$
That is, amplification factor is 4.
