What is the effect of thermionic emission on the conductivity of a metal?.
- A.It decreases conductivity
- B.It has no effect on conductivity
- C.It increases conductivity
- D.It makes the metal an insulator
Model answer
What a good answer should say
- It increases conductivity
Explanation
Why this works
Thermionic emission increases the number of free electrons available for conduction in the metal. As more electrons are released, the conductivity of the metal improves, allowing for better electrical performance in devices that utilize thermionic emission.
