*REVIEW CIRCUIT SYMBOLS AND DIAGRAMS*
*REVIEW HOW TO DRAW ELECTROSTATIC DIAGRAMS FOR FRICTION, CONTACT AND INDUCTION*
Conductor
Allows the flow of electrons
Current electricity
An electrical charge that moves. Usually found in conductors.
Electrical Circuit
A continuous path in which electrons can flow
Electrostatic Series Tables
A table that displays which materials have a stronger and weaker hold on their electrons.
Weaker= Positive
Stronger= Negative
In friction, how do both materials look before and after?
Before: Both materials are neutral
After: One material is Positive and one material is negative
In contact, how do both materials look before and after?
Before: One material is positively or negatively charged and the other is neutral
After: Both materials are neutral
In induction, how do both materials look before and after?
Before: Neutral electroscope and a positively or negatively charged object
After: Negative objects will make the electrons in the knob move further away and positive objects make electrons move into the knob, move closer to the object.
Parallel
There are two or more paths for the electrons to flow through
Series Circuit
The electrons flow in a straight line
Insulator
Doesn’t allow a flow of electrons
Static Electricity
The charge stays in one place. Usually found on insulators.
What are the 3 laws of electric charges?
1) Opposite Charges Attract
2) Like Charges Repel
3) Neutral Charges Neither Attract Nor Repel
What are the 3 ways to make a static charge?
1) Friction
2) Contact
3) Induction
