For a given plate-voltage, the plate current in a triode is maximum when the potential of
A
The grid is positive and plate is negative
B
The grid is positive and plate is positive
C
The grid is zero and plate is positive
D
The grid is negative and plate is positive
Answer
The grid is positive and plate is positive
Explanation
Solution
When grid is given positive potential more electrons will cross the grid to reach the positive plate P. Hence current increases.
