What are the factors on which the rate of thermionic emission depends?

Text Solution

Verified by Experts

The rate of thermionic emission depends on the temperature and work function of the metal. Higher the temperature, greater will be thermionic emission. For metals with lower work function, thermionic emission occurs at low temperature.
