1. Considering any circuit discuss the application of zener diode as voltage regulator. What
would be the impedance of zener diode in case of current is greater than Izm. Calculate
the zener impedance if the zener diode voltage varies from 5.72 V to 5.98 V when the
current changes from 8.00 mA to 14.0 mA.

Answer:
Zener diodes are used for voltage regulation, as reference elements, surge suppressors, and in switching applications and clipper circuits. The load voltage equals breakdown voltage VZ of the diode. The series resistor limits the current through the diode and drops the excess voltage when the diode is conducting.....
hope it helps bye
