Dynamic Resistance -

R_{d}= \frac{dv}{di}

- wherein

Since slope of potential vs current graph is non uniform hence resistance keep changing .

 

Current through 10k\Omega, I2 = \frac{50}{10K} = 5mA

Current through 5k\Omega , I = \frac{120-50}{5K} = 14mA

Current through Zener = I - I2 = 14 - 5 = 9mA


Option 1)

5\: mA

Option 2)

14\: mA

Option 3)

9\: mA

Option 4)

Zero
