# Calculate the Amplification Factor of a Triode Valve that Has Plate Resistance of 2 Kω and Transconductance of 2 Millimho. - Physics

ConceptTriode

#### Question

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

#### Solution

Given:-

Plate resistance,

r_p=2kOmega

Transconductance of plate,

g_m=2"mili mho"=2xx10^-3"mho"

Therefore, the amplification factor is given as:-

mu=r_pxxg_m

mu=2xx10^3xx2xx10^-3=4

That is, amplification factor is 4.

Is there an error in this question or solution?
