Factors Affecting the Rate of Thermionic Emission | Electronics

Factors Affecting the Rate of Thermionic Emission | Electronics Form 5 Physics KSSM Chapter 5 - Electronics Thermionic emission is a process of emission of charge particle (known as thermion) from the surface of a heated metal. The rate of emission (number of electrons emitted in 1 second) is affected by 4 factors, namely a. the temperature of the heated metal, b. the surface area of the heated metal, c. the types of metal d. the coated material on the surface of the metal.
