ELECTRICITY! PART 1 – ELECTRIC CHARGE AND STATIC ELECTRICITY
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
AN ELECTRIC FIELD is a region around a charged object where an electric force is exerted on other charged objects.
We also know that the buildup of charges on an object is called STATIC ELECTRICITY
There are four ways that a static charge can build up: 1. Friction 2. Conduction 3. Induction 4. PolarizationRemember! Friction – Objects rubbed together.Conduction – The objects touchInduction – The objects do not touch
Static Discharge refers to the loss of static electricity as electric charges transfer from one object to another. Static discharge often produces a spark!
Lightening bolts form when negative charges at the bottom of clouds build up and the Earth’s surface becomes positively charged.
Electrons jump between the clouds and Earth’s surface, producing a giant spark of lightening.
