Static Electricity
This occurs when two different neutral materials are rubbed together and electric charges are transferred from one object to the other
Friction
Using two metal leaves, I am a
Protons are always kept in the
Nucleus
Placed on top of buildings to provide a safe path for lightning to follow to the ground
Lightning Rods
When silk is rubbed on ebonite, which becomes negatively charged? (no double tries)
Ebonite
A small neutrally charged sphere suspended on a string will be attracted to a
If the atom does not have an equal number of protons and electrons, the atom then has an
Electric Charge
Materials that inhibit or prevent the movement of electrons.
Insulators
Two objects with different amounts of electric charge come in contact and electrons move from one object to the other.
Conduction
An electroscope composed of a small sphere suspended on a piece of string is known as a
Pith Ball Electroscope
Materials that allow the movement of electrons
Conductors
Non-metallic substances that can conduct
Semi-Conductors
Charging a neutral object by bringing another charged object close to, but not touching, the neutral object.
Induction
Insulator
An instrument that detects electric charges
Electroscope
Neutral objects are attracted to charged objects because of a phenomenon known as:
Induced Charge Separation
An object can be charged permanently through
Grounding
Electroscopes utilize this phenomenon to show you if a charge is present
Induced Charge Separation
Rapid transfer of excess charge
