P6 - Diodes and Rectification

Question 1

What are diodes?

Answer 1

something that only lets the current flow in one direction.

Question 2

What are Diodes made from?

Answer 2

Semi-conductors such as silicon

Question 3

Where can you use diodes?

Answer 3

to rectify alternating current

Question 4

What is half-wave rectification?

Answer 4

when a single diode only lets thro current in half of the cycle

Question 5

How do you get full-wave rectification?

Answer 5

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
