On applying a potential of – 1 volt at the grid of a triode, the following relation between plate voltage V p (volt) and plate current 
is found 
If on applying – 3 volt potential at grid and 300 V potential at plate, the plate current is found to be 5mA, then amplification factor of the triode is
Text Solution
Verified by ExpertsThe correct answer is:
A
At 
and 
At 
for constant plate current i.e. 
From 
⇒ ⇒ 
⇒ ⇒ 
∴ ∴ change in plate voltage 
Change in grid voltage
