In the given circuit, the current through zener diode is: [JEE Main 16-4-2018]
A) 2.5 mA
B) 3.3 mA
C) 5.5 mA
D) 6.7 mA
Correct Answer: B
Solution :
the current through 500 ohm resistor is 0.01 ampere as voltage across is 5V. the current through 1500 ohm resistor is 0.0067 ampere so the current through zener diode is difference in current through these resistors. so the current is \[0.01-0.0067=0.0033\]ampere. so the correct answer is B.
