New cards

Diode

Current through the diode flows in one direction only.

This is because the diode has a very high resistant in the reverse direction

2
New cards

Current/ potential difference graph of a diode

Flat line until slightly into psoitive then rises

New cards

What are diodes extremely useful for

Controlling the flow of current in circuits

4
New cards

Symbol of LED

Same as diode but with 2 arrows pointing out of top right

5
New cards

How is LED simialri to diode

Only allows current to flow in forward direction

6
New cards

What does an LED do

Gives off light when a current flows through.

LEDs are an extremely energy efficient source of light
