In the given circuit the current through zener diode is:

In the given circuit the current through zener diode is:

In the given circuit the current through zener diode is:

Options

A $3 . 3mA$
B $2 . 5mA$
C $5 . 5mA$
D $6 . 7mA$

Correct answer

A. $3 . 3mA$

Step-by-step solution

{V}_{AB} = 10V∴ {V}_{BC} = 5V

, the current in

{R}_{1} = {I}_{1} = \dfrac{5}{500}

⇒ {I}_{1} = 10mA

. Current in

{R}_{2} = {I}_{2} = \dfrac{10}{1500}⇒ {I}_{2} = \dfrac{20}{3}mA

Current in zener diode =

{I}_{1} - {I}_{2} = \left(10 - \dfrac{20}{3}\right)mA = \dfrac{10}{3}mA

In the given circuit the current through zener diode is:
