P6 - Diodes and Rectification Flashcards
1
Q
What are diodes?
A
something that only lets the current flow in one direction.
2
Q
What are Diodes made from?
A
Semi-conductors such as silicon
3
Q
Where can you use diodes?
A
to rectify alternating current
4
Q
What is half-wave rectification?
A
when a single diode only lets thro current in half of the cycle
5
Q
How do you get full-wave rectification?
A
Use a bridge circuit with 4 diodes so in this circuit the current always flows thro component in same direction and output voltage has same sign
