What is the current flowing through 1 K`Omega` restsor in the following circuit ?

A

2 mA

B

3 mA

C

4mA

D

5 mA

Text Solution

Verified by Experts

The correct Answer is:
D
This is a zener diode circuit. Zener voltage = 5 V. Zener diode is used as a voltage regulator.
`therefore` Voltage across 1 `K Omega` resistance = 5 V
`therefore I=5/10^3 = 5xx10^(-3)`=5 mA
