Law of Electric Charges
Unlike charges attract or repel
Attract
Objects lower on the series gains/loses electrons?
Gains electrons
When does friction occur?
When 2 different objects are rubbed together.
When a charged object comes in contact with or near another object, will the electrons transfer from one object to another or stay the same?
Electrons can move from one on heat to the other
What’s an electroscope?
Device that detects and identify a static charge.
Neutral, Neutral
attract, repel or nothing
Nothing
Does acetate have a stronger/weaker hold on its electrons?
Weaker hold (placed highest on the series)
Object loses electrons becomes negatively/positively charged?
Positively
What’s an insulator?
Allows charges to be built up on it
What’s discharging?
When electrons are added/removed from an charged object to restore a neutral charge
What are 3 ways objects can be charged?
- Charging by friction
- Charging by contact (conduction)
- Charging by Induction
Does ebonite have a strong/weak hold on electrons?
Strongest hold ( bottom of the series)
Stronger hold on electrons gains electrons and becomes -ve/+ve?
Negatively charged (-ve)
What’s a conductor?
Allows electrons to move freely through an object.
What’s electrical conduction?
The movement of electric charges from one place to another
