Question 1

An 8 V Zener diode voltage regulator as shown in figure below operates from a source that varies from 12 V to 18 V. The series resistance is 100 Ω and the load draws current that varies from 0 mA to 30 mA . The power dissipation in Zener diode under worst-case condition is

Question 2

For the circuit shown below, assume that the Zener diode is ideal with a breakdown voltage of 6 volts. The waveform observed across R will be?

Question 3

In a voltage regulated power supply the Zener operates in the breakdown region when (Vin is input voltage and Vz is Zener breakdown voltage)?

Question 4

For the diode circuit shown below average output voltage V0 is __________ volts. Consider all elements are ideal.

Question 5Multiple Correct Options

For the Zener Regulator shown in figure below:

Consider the following parameters as follows:

Then choose the correct option(s):

Question 6

In the given voltage regular load current can vary from 100mA to 600mA. Assuming Zener diode is ideal, the value of R is

Question 7

The Zener Potential of a Zener diode is very sensitive to temperature. Analyze the change in 10 V zener diode if the temperature is increased to 100 C. Given, temperature coefficient = |0.072| / degree centigrade and initial temperature was 25 C where || represents absolute value function.
