What Is Electricity? A form of energy made up of charges that can produce light, heat, or motion

Kinds of Electricity Static An electric charge that collects or builds up on the surface of an object Examples –Shocking –Lightening Current The flow of electric charges carried through a material such as wire or other conductors Examples –Power lines –Computers –Appliances

Conductors and Insulators Conductors Any material that allows electric charges to move through it Examples: –Metals (esp. copper) –Your body –Electric wires Insulators Materials that do not allow electric charges to flow freely through them Examples: –Wood –Glass –Rubber

Lightning kills more than 60 people injures more than 400 people a year in the US one mile every five seconds about 50,000 F
