Relations between Tube Parameters

The plate current in a triode valve is a function of plate voltage e_p and grid voltage e_g.

Thus,

If the grid and plate potentials are changed in such a way that di_p = 0, it can be written as:

                μ = r_pg_{m                   .............(1)}

_{So, amplification factor is the product of plate resistance and mutual conductance.}
