1

Sign for a diode

--(|>|)---

--(▶️I)---

2

When does a diode conduct?

-when the positive part is connected to the negative terminal and vice versa
-this is called forward bias (opposite is reverse bias)

3

Forward bias

When a diode allows electricity to flow through a circuit

4

Reverse bias

When a diode does not allow electric yt to flow through it

5

Light emitting diode (LED) function

-Shows that current if flowing through a circuit
-needs a resistor as it only uses a v small a amount of electricity

6

What does LED stand for?

Light emitting diode

7

What is the sign for an LED?

Same as diode but with two arrows protruding from the top left hand corner

/ /

8

What does LDR stand for?

Light dependant resistor

9

Function of an LDR?

-resistance decreases if the LDR senses a lot of light shining on it
-resistance will increase of the LDR senses darkness

10

Diode

-allows current to flip in one direction only
