1
New cards
Electrostatics
Study of electric charges in stationary form.
2
New cards
Smallest Units of Charge
Electron (-) and proton (+).
3
New cards
Charge of Electrons and Protons
Equal in magnitude but opposite in sign.
4
New cards
Electric Charge and Ions
Electrons move from atom to atom to create ions.
5
New cards
Cations (+)
Loss of electrons results in a positively charged ion.
6
New cards
Anions (-)
Gain of electrons results in a negatively charged ion.
7
New cards
Neutral Atom
Has no net charge because protons and electrons are balanced.
8
New cards
Electrification
Occurs when an object becomes charged by the removal or addition of electrons.
9
New cards
Electrification by Contact
Direct connection causes the flow of electrons.
10
New cards
Electrification by Friction
Buildup of electrons caused by rubbing objects together.
11
New cards
Electrification by Induction
Using the electric field of a charged object to confer a charge on an uncharged object.
12
New cards
Electrified Object
Has too few or too many electrons, example: static electricity.
13
New cards
Movement of Electric Charges
Positive charges do not move
14
New cards
Smallest Unit of Electric Charge
Electron (-).
15
New cards
Fundamental Unit of Electrical Charge
Coulomb (C).
16
New cards
Value of One Coulomb
1C = 6.3 × 10^18 electron charges.
17
New cards
Charge of One Electron
1.6 × 10^(-19) C per electron charge.
