For the circuit shown below, the current through the Zener diode is

For the circuit shown below, the current through the Zener diode is

For the circuit shown below, the current through the Zener diode is

Options

Azero.
B $5mA$ .
C $9mA$ .
D $14mA$ .

Correct answer

C. $9mA$ .

Step-by-step solution

For the circuit shown below, the current through the Zener diode is

Current through

5kΩ

,

{i}_{1} = \dfrac{70}{5000} = 14mA

Current through

10kΩ

,

{i}_{l} = \dfrac{50}{10000} = 5mA

Current through the Zener diode,

I = 9mA
