Question

Once a zener diode is taken in its breakdown region, there is not much change in it’s
A. Current
B. Resistance
C. Voltage
D. Capacitance.

Answer 1

Hint: There are number of conductors in the electrical and electronics, the diode is the type of semiconductor that will allow the current to flow only in one direction and it has two terminals P and N types. As same as diode, there is a special diode called Zener diode, it is one of the semiconductors diodes that consists of two terminals p and n which is used to allow the current in two directions.

Complete step by step answer:
The zener diode consists of two terminals p and n, we can allow the current in forward direction and reverse direction, the usage depends upon the place or device where we have to use it.
As we know that the graph of the zener diode is represented by current and the voltage, the current (i) is represented in the y-axis and voltage (v) is represented on the x-axis.
So when the current is allowed to flow through the zener diode or the zener diode is taken in its breakdown region then we find the change of current will be more, it slowly increases and suddenly takes the high peak but when it comes to the voltage, there will be no notable change can be seen.
Therefore, once a zener diode is taken in its breakdown region, there is not much change in its voltage.
It means the option is (C) is correct.

Note: In this solution we may need to be aware about the concepts diode and zener diode, we should go through the terminals usage, forward and reverse bias in the zener diode. If we are clear about these concepts then we can answer this question.
