Question

In Zener diode, which scenario causes a large change in current and what is its impact on Zener voltage?


Ops:



When applied reverse bias voltage reaches breakdown voltage and Zener voltage remains constant.


When breakdown voltage is greater than applied reverse bias voltage and Zener voltage


increases


When all applied reverse bias voltage, breakdown voltage and Zener voltage remains constant.


When breakdown voltage is lesser than applied

Answer 1

Answer:

Option A

is the correct answer .

at zener break down

zener voltage becomes constant

Answer 2

In Zener diode, When applied reverse bias voltage reaches breakdown voltage and Zener voltage remains constant causes a large change in current

Option a

Explanation:

• zener diode is a diode however unlike the original diode which allows the current flow only in One Direction zener diode has a capacity to allow the flow of current in both of the direction.

• when the current flows in the reverse direction it is known as reverse bias. if the voltage reaches the voltage breakdown voltage the Zener voltage remains constant and results in a large change in the current flowing through it
