Symbol for current

Capital i

4

What is voltage?

Electric potential energy
-comes from the source

5

Relationship between voltage and current

Current is directly related to voltage
(Current will go up if voltage goes up)

6

Resistance

The property of any material that slows down the flow of electrons in a circuit and can react it to other forms of energy
