Q. Define amplification factor?

Amplification factor  μ

It is the ratio of the drain -source voltage (ΔVDS) to the change in the gate to source voltage (ΔVGS) at constant drain current .
Amplification factor,μ ΔVDS ΔVGS  at constant ID.

Ampilification factor of a JFET  indicates how much more control  the gate voltage has over drain current than has the drain voltage.
μ = ΔVDS / ΔVGS
multiplying the numerator and denominator on R.H.S  by ΔID,
we get

μ = (ΔVDS / ΔVGS)*(ΔID / ΔID) = (ΔVDS / ΔID) * (ΔID / ΔGS)

μ = rd * gfs

ie

amplification factor = ac drain resistance * transconductance
