The random motion of holes and free electrons due to thermal agitation is called______________?
Correct answer: A. Diffusion
- A. Diffusion
- B. Pressure
- C. Ionisation
- D. None of the above
Explanation
Thermal agitation gives carriers random motion, and their net movement from a region of higher concentration to lower concentration is called diffusion. Ionisation instead refers to producing charged particles by removing or adding electrons.
