In the given circuit, the voltage across the load is maintained at 12 ~V . The current in the zener diode varies from 0-50 ~mA . What is the maximum wattage of the diode?

Options

  1. A12 ~W
  2. B6 ~W
  3. C0.6 ~W
  4. D1.2 ~W

Correct answer

C. 0.6 ~W

Step-by-step solution

In the circuit, the zener diode is used as power regular therefore, P=V I=12 0.05=0.6 ~W
