Answer 1

Answer:

Explanation:Internal field emission is also known as zener break down. Zener diode is the heavily doped on junction diode.---this sudden increase in current is known as zener break down or internal field emission.And this increase in current can be controlled by varying the voltage so zener break down does not damage the diode
