Static Electricity

A build up of electrical charges on an object

Current Electricity

A flow of electric charge.

Electrical Charge

electrical particles that are negatively charge

Circuit

A system that provides a pathway for electrical current to flow through

cell

Supplies energy to circuit, by pushing current from the positive to negative end

voltmeter

A device used to measure voltage, or electrical potential energy difference

	Static electricity	Current electricity
What is it caused by?	An imbalance of positive and negative charges,	The movement of electrons through a wire.
Do the negative charges move?	Yes	No
Does it power appliances?	No	Yes

What are some examples of static electricity:

• Walking on carpet
• Lightning
• Trampoline
• Rubbing a balloon on your head

How does the Van der Graaff machine work?

It pulls electrons from the earth and moves them along a belt then stores it in a sphere.

What was one of the experiments we did with the machine?

People put both of their hands onto the top of the sphere and they're hair would go up.

Why does it do this?

The charges transfer to the persons body.
