What is Static Electricity?

Section 11.1

Page 2: What is Static Electricity? Section 11.1. Recall… All matter is made up of atoms –Protons – positive charge in nucleus –Neutrons – neutral charge in nucleus.

Recall…• All matter is made up of

atoms– Protons – positive

charge in nucleus– Neutrons – neutral

charge in nucleus– Electrons – negative

charge around nucleus

Electrical Charge• If an atom has imbalance of electrons and

protons it is said to have an electrical charge– Positive objects have fewer electrons than

protons– Negative objects have more electrons than

protons

Law of Electric Charges• Like charges will repel• Unlike charge will attract

Static Electricity• An imbalance of electric charge on the

surface of an object• Balloon demo

– Hair becomes positive– Balloon is negative– The wall is neutral

Ways to Check for Charges• Electroscope – a piece of

equipment used to detect electrical charges– Pith-Ball Electroscope– Metal Leaf Electroscope
