1

What are the two types of charge?

Static and moving

2

Electric load

A device that transforms the electric energy into other forms of electricity
Examples: oven-heat, speakers-sound, fan-wind

3

Electric curcut

A complete pathway for electrons that allow current to flow so electric energy works.

4

How does a chemical cell work?

Chemical energy in a cell gives electrons on the negative terminal electric potential energy.
-electrons are attached to positive terminal
-when electrons reach the positive terminal the circuit is complete

5

The 4 basic parts to a circuit

Source, conductor, load, switch

6

Source

The source of electrical energy
Example: cell, battery

7

Conductor

The wire through which current flows

8

Load

A device that transforms the electric energy into other forms of electricity

9

Switch

A device that can turn the circuit on or off by closing or opening the circuit

10

Current electricity

A continuous flow of charge
-only works when there is a complete circuit for e- to flow

11

How does current flow?

Electrons are bumped

12

Current-measure of flow

Unit of flow for electric current is amperes (A)
