Static electricity and moving electricity- electric current

2

Electric energy

-can be used to do work
- appliances,ipads, lights, cooking, etc.

3

Sources of electrical energy

Electrochemical cell or battery

4

Electrochemical cell

Converts chemical energy to electrical energy to be used for work

Battery

A bunch of electrochemical cells connected together

6

Electric potential energy

Electric energy that is stored in a battery

7

Law of the conservation of energy

-energy can't be created or destroyed
- it can only be transformed from one form to another
