Question

Consider the circuit, the current through the Zener diode is

$20 m A$
$10 m A$
$15 m A$
$40 m A$

A

20 m A

B

10 m A

C

40 m A

D

15 m A

Solution

Verified by Toppr

The correct option is B $10 m A$
Voltage across Zener diode is constant
$i_{R_{2}} = \frac{20}{2000} = 0.01 A$
$i_{R_{1}} = \frac{(40 - 20)}{2000} = 0.01 A$
