Question
A triode valve has an amplification factor of 20and its plate is given a potential of 300V. The grid voltage to reduce the plate current to zero -is
Options
A.25V
B.15V
C.12V
D.10V
Solution
Amplification factor = 20 =
= 20
⇒ V = 
= 15V
= 20
⇒ V = = 15VCreate a free account to view solution
