In the given circuit, the current through the resistor `4kOmega` is

A

1 mA

B

3 mA

C

5 mA

D

4 mA

Text Solution

Verified by Experts

The correct Answer is:
B

In the circuit, Zener diode is used as a power regulating device. Therefore, the current in the circuit, `l=(12V)/(4kOmega)=3xx10^(-3)A=3mA`
