Question

How will the thermionic current vary if the filament current is increased?

Answer 1

Answer:

If the filament current is increased, it will increase the temperature of the cathode (metal) and the cathode will emit more electrons. This will lead to an increase in the number of thermions emitted per unit time. As a result, the thermionic current will increase.

Answer 2

The filament current is raised, the cathode (metal) temperature will increase, and more electrons will be released by the cathode.

Explanation:

• When the filament current is raised, the cathode (metal) temperature will increase, and more electrons will be released by the cathode.
• It will cause the rate of thermions released per unit time to increase. As a consequence, they will increase the thermionic current.

Cathode:- The cathode is the electrode, which is charged negatively. The cathode draws cations or positively charged. The cathode is an electron source or maybe an electron donor.
