Question

In the given circuit the current through zener diode is:

Choose an option

Show full solutionCorrect option: A
Correct answer
A3.3 mA

Step-by-step explanation

VAB=10 V∴VBC=5 V, the current in R1= I1=5500
⇒I1=10 mA. Current in R2= I2=101500⇒ I2=203mA

Current in zener diode = I1- I2=10-203 mA=103 mA
