-10

5

What are the three main parts of an electric circuit?

Source, path, device 

+20

B

1

Static electricity happens when:

Electric charges build up on an object 

-20

2

What type of circuit allows electricity to travel along multiple paths?

-20

3

What is the flow of electrons called?

Electric current 

+10

4

+10

5

An object with too many electrons is:

Negatively charged 

+10

C

1

An object with too few electrons is:

Positively charged 

-10

2

What is the main difference between static electricity and current electricity?

-20

3

Why are electrical wires coated in rubber or plastic?

To prevent electric current from escaping
