Static Electricity - Mind Map

Static Electricity

Charging by Friction

definition: charging by fricton a when you rub some thing like rubber and fur, the rubber will take electrons from the fur leavign both objects with an imbalance of electrons.

Charging by Contact

negative rod

definition

when charging both objects start off neutral and end
off with differet charges. for example:if i used fur and
ebonite after contact the ebonite would take some of the furs negative electrons then the fur might become a positively charged

a helpful video:

positive rod

definition

when charging with contact both objects start off neutral
and end off with different charges. for example: if i rubbed nylon on rubber the negative charges will go over to the rubber but the positive charges will stay in both objects evenly because POSITIVE CHARGES DONT MOVE!!!

Charging by Induction

Temporary Induction

Defenition: temperary induction is when an negativly
charged rod is brought near a neutral rod and the negative electrons in the neutral rod move to the far side, and when the negative rod is removed the eletron spread themselfs ot again.

Permanent Induction

Definition: permanet induction is when a negative rod
is brought near a neutral sphere, when that happens the negative charges flow out the grounding wire and the negative rod is removed, then the sphere is now PERMANETLY positively charged
