Charging by friction |
Occurs when two neutral materials are rubbed together or come in contact and electrons move from one object to another. |
Rub |
|
|
Give up electrons makes it... |
Positively charged |
|
|
|
Attracting electrons makes it... |
Negatively charged |
|
|
|
Induction |
Passing electricity without touching |
|
|
|
Conduction |
When you pass electricity with friction |
|
|
|
Series |
There is only one pathway around circuit electrons must follow the leader |
|
|
|
Parallel |
There is more then one pathway and electrons can chose where they want to go |
|
|
|
Series circuit rules |
V is added I is equal R is added |
|
|
|
Parallel circut |
V is equal I is added V divided by I is R |
|
|
|
Ohms law |
V=IR |
|
|
|
Charging by induction |
Charging a neutral object by bringing a charged object close to but not touching it. |
Balloon and wall |
|
|
Permanent induction |
Bring a charged object towards the netraul causes the electrons to move away and ground the excess electrons making it positive |
|
|
|
Charging by conduction |
Charging by conduction occurs when two objects with different amounts of electrical charge come in contact and electrons move from one object to another |
|
|
|
Physical properties |
Description of a substance that helps to identify it. |
|
|
|
Resistor |
A device that reduces the flow of the electrical current |
|
|
|
Current |
The flow of electricity through a conducter |
|
|
|
Ion |
A charged particle |
|
|
|
Ionic compound a compound that consists of positively and negitivly charged ions |
H²O |
|
|
|
isotope |
an atom with the same number of protons but different number of neutrons |
|
|
|
Red shift |
The light from galaxies far away shifting towards the red end of the colour spectrum indicating that the galaxies are moving away from earth |
