Question

What is thermonic emission? Explain the behaviour
of electrons in the
presence of electric field?​

Answer 1

Answer:

Thermionic emission is the liberation of electrons from an electrode by virtue of its temperature. This occurs because the thermal energy given to the charge carrier overcomes the work function of the material.

Behavior of protons, neutrons and electrons in electric fields. ... Protons are positively charged and are thus deflected on a curving path towards the negative plate. Electrons are negatively charged and are deflected on a curving path towards the positive plate. Neutrons have no charge, and continue on in a straight line.
