Q. Avalanche breakdown in zener diode is __

A
electric current multiplication takes place
B
phenomenon of voltage multiplication takes place
C
electrons are decelerated for a period of time
D
sudden rise in voltage takes place.
Solution:

The carriers in transition region are accelerated by electric field to energies. That energies are sufficient to create electron current multiplication. A single carrier that is energized will collide with another by gaining energy. Thus an avalanche multiplication takes place.
