Law of Electric Charges
- Like charges repel;
- unlike charges attract.
- Neutral objects are attracted to charged objects
Charging by Friction
Rubbing two objects together causes one object to lose electrons & the other to gain them.
Charging by conduction
A neutral object is touched to a charged object & it gains the same charge as the charged object.
Charging by Induction
A neutral object is placed near a charged object & becomes charged without physically touching. The electric field causes electrons to rearrange themselves.
An object that becomes charged by contact always gets the same type of _______ on the object that is providing it.
An object that becomes charged by contact always gets the same type of charge on the object that is providing it.
Induction example?
- If you place a positive rod close to a neutral object what would happen to the electrons on the neutral object? Resulting to what on what end and what on the other end?
Place the positive rod close to the neutral object & the electrons on the neutral object will be drawn toward one end leaving a negative side and a positive side.
An object charged by induction always has the ______ charge of the object providing the charge
An object charged by induction always has the opposite charge of the object providing the charge
