Deck 46: The Zener Diode

Question 1

When a diode is broken down in the reverse direction, it enters what is known as the ____________________ region.

Answer 1

zener

Question 2

What is the voltage drop of a device connected parallel to a zener diode?

Answer 2

Since the voltage drop of the zener diode is constant, any device connected parallel to the zener will have a constant voltage drop even if the current through the load is changing.

Question 3

Usually, when a diode is broken down into the zener region, it is ____.

A) converted into a zener diode
B) destroyed
C) converted into a rectifier
D) converted into a resistor

Answer 3

B

Question 4

The zener diode makes a very effective voltage regulator for the load circuit.

Question 5

The zener diode is a special device designed to be operated with forward polarity applied to it.

Question 6

The zener diode can be tested with an ohmmeter in the same manner as a common junction diode is tested, provided the ____ than the battery voltage of the ohmmeter.

A) zener voltage is less
B) zener voltage is greater
C) ground voltage is greater
D) ground voltage is less

Question 7

The voltage drop of the zener diode is ____________________.

Question 8

What is the relationship between supply voltage and zener voltage?
