Question

The plate current in a triode value is maximum when the potential of the grid is
(a) positive
(b) zero
(c) negative
(d) non-positive

Answer 1

the answer is option a) positive

Answer 2

The plate current in a triode value is maximum when the potential of the grid is positive.

Explanation:

Option (a) Positive is correct answer.

• When the grid voltage is positive, it will make the electrons travel towards to the anode, which will allow the current to increase.
• Therefore, when the grid's potential is positive, the surface current in triode value is optimum.  therefore option (a) positive is correct answer.

Triode:- Electron coil formed of three filaments of the electrodes-cathode, anode plate, and grid control placed in an evacuated glass or metal container. It can be used in both radio and audio signals, as such an oscillator, and also in electronic loop or circuits as an amplifier.
