thermionic effect

thermionic effect

1. It is produced by the spillover of electrons when heating a metal to high temperatures.

2. the electron cloud generated by the detachment of electrons from the metal is brought to the anode by means of a potential difference

3. It is caused by a thermal energy that causes an electrostatic force and pushes the electrons towards the surface.

4. When the negative diode reaches the incandescent state, it emits electrons with a negative charge, which are attracted by the positive diode.

5. There is something necessary for the effect which is called a valve and its function is to convert alternating current into direct current.
