Electronic Devices Question 184

Question: The grid voltage of any triode valve is changed from -1 volt to - 3 volt and the mutual conductance is 3×104 mho. The change in plate circuit current will be

[MNR 1999]

Options:

A) 0.8 mA

B) 0.6 mA

C) 0.4 mA

D) 1 mA

Show Answer

Answer:

Correct Answer: B

Solution:

By using gm=ΔipΔvg
