Static Electricity

Static Charge

imbalance of electric charge on an object

Objects that are positively charged

When it has lost electrons, it now has more protons than electrons.

Objects that are negatively charged

When it has gained electrons, so it now has more electrons than protons

Objects are neutral

When it has the same number of electrons and protons

You can't

lose or gain protons

Objects with the same charge...

...repel eachother

Objects with opposite charges...

...attract eachother

Neutral objects...

..will be attracted by positively or negatively charged objects

Two neutral objects...

...will neither repel nor attract each other

Charging by friction

two different neutral objects rub together and one becomes positively charged and the other becomes negatively charged

The lower on the electrostatic lest the stronger tendency to gain electrons

Charging by conduction

Charging an object by contact with a charged object

Grounding

Connecting an object to a large body, like earth that is capable of effectively removing an electric charge that the object might have

Induction

Charging objects without contact

Conductors

Materials that allow electric charges to flow through them easily

Insulators

materials that prevent electric charges from flowing through them easily

Electric Discharge

The rapid transfer of electric charge from one object to another
