ELECTRICITY! PART 1 – ELECTRIC CHARGE AND STATIC ELECTRICITY
2
WE KNOW THE FOLLOWING : THE CHARGE ON A PROTON IS (+) THE CHARGE ON AN ELECTRON IS (–) CHARGES THAT ARE THE SAME REPEL CHARGES THAT ARE DIFFERENT ATTRACT THE FORCE BETWEEN CHARGED OBJECTS IS CALLED AN ELECTRIC FORCE
3
AN ELECTRIC FIELD is a region around a charged object where an electric force is exerted on other charged objects.
4
We also know that the buildup of charges on an object is called STATIC ELECTRICITY
5
There are four ways that a static charge can build up: 1. Friction 2. Conduction 3. Induction 4. Polarization Remember! Friction – Objects rubbed together. Conduction – The objects touch Induction – The objects do not touch
6
Static Discharge refers to the loss of static electricity as electric charges transfer from one object to another. Static discharge often produces a spark!
7
Lightening bolts form when negative charges at the bottom of clouds build up and the Earth’s surface becomes positively charged.
8
Electrons jump between the clouds and Earth’s surface, producing a giant spark of lightening.
