Analog Electronics

38.

In figure the zener has a resistance of 5 ohms. As the load resistance is varied, the output voltage

will remain constant at 12 V

will vary between 12.05 and 12.65 V

will vary from 10 to 20 V

will remain constant at 12.05 V

Answer: Option

Explanation:

V₀ = 12 + I_z x 5, Max I_z = 130 mA, minimum I_z = 10 mA.

Answer is right but it has not mention current through the zener diode which is taken 130mA.

I think the voltage across load should remain constant at 12 volts.
