Electricity

What is electricity?

• an object that electrons do not flow through

• energy created by moving charged particles

• when two objects repel each other

• a circuit that has only one path for electricity to flow

Two types of circuits are

• parallel and magnetic
• electromagnetic and series
• series and parallel

____________ stops the flow of electricity.
