When load current is zero, the Zener current will be_____________?

A. Zero
B. Minimum
C. Maximum
D. None of the above

Categories Regulated D.C. Power Supply

A power supply can deliver a maximum rated current of 0.5 A at full-load output voltage of 20 V. What is the minimum load resistance that you can connect across the supply?

In a regulated power supply, two similar 15 V zeners are connected in series. The input voltage is 45 V d.c. If each Zener has a maximum current rating of 300 mA, what should be the value of the series resistance ?
