Zener Diode, Electrical Engineering

Assignment Help:
A Zener diode has the specifications VZ=6.8V and PDmax.=500mW. Assume RZ=0.

(a) Find the maximum allowable current iZ when the Zener diode is acting as a regulator.

(b) If a single-loop circuit consists of an ideal 16-V dc source VS, a variable resistor R and the described Zener diode, find the range of values of R for which Zener diode remains in constant reverse breakdown with no danger of failure.
