Chapter 3, Section 2 Flashcards
1
Q
What is the process of an AC signal when it passes a diode?
A
Only the positive or negative half-cycle passes, the other is blocked.
2
Q
What doped material make up the anode and the cathode segments of a diode?
A
Anode = P-doped material
Cathode = N-doped material.
3
Q
When looking at the physical diode, how do you determine the cathode end?
A
It has a stripe or band on the body.
4
Q
How much forward bias is required normally to get a P-N silicon diode flowing?
A
0.6 to 0.7 volts.
5
Q
What is the condition a diode is in when current is forced against the anode?
A
Forward bias.
6
Q
What is a very common use of diodes in electrical circuits?
A
Rectification, voltage regulation, and signal demodulation.
