Question 1

What is a diode?

Answer 1

A diode is a semiconductor device that allows current to flow in one direction.

Question 2

What is the left side of the diode called?

Answer 2

Anode (P type semiconductor material)

Question 3

What is the right side of a diode called

Answer 3

Cathode(N type semiconductor material)

Question 4

When connecting a diode where must the anode and cathode connect to?

Answer 4

The anode connects to the positive and the cathode connects to the negative.

Question 5

What is it called when current is travelling forward through a diode?

Answer 5

Forward bias mode

Question 6

What’s it called when current is travelling backwards through a diode?

Answer 6

Reverse bias mode

Question 7

How much voltage do we need to make a diode conduct?

Answer 7

.7 volts

Question 8

What is bulk resistance and how is it measured?

Answer 8

Bulk resistance is the total resistance of a diode and its measured by adding the R value of positive and negative materials
