On applying a potential of at the grid of a triode, the following relation between plate voltage and plate current (in ) is found . If on applying potential at grid and potential at plate, the plate current is found to be then amplification factor of the triode is |
On applying a potential of at the grid of a triode, the following relation between plate voltage and plate current (in ) is found . If on applying potential at grid and potential at plate, the plate current is found to be then amplification factor of the triode is |
At and
At for constant plate current
From
change in plate voltage
Change in grid voltage
So,
