1
Electricity
The phenomenon caused by the presence or movement of electrically charged particles which exert an electrical force.
New cards
2
Electrostatics
A division of electricity characterized by the accumulation of charged particles on the surface of a substance.
New cards
3
Electrodynamics
A division of electricity characterized by the flow of electrons through a conductor.
New cards
4
Atom
The basic unit of a chemical element, consisting of a nucleus and electrons surrounding it.
New cards
5
Electric Charge (q)
A fundamental property of matter, carried by subatomic particles, classified as positive or negative.
New cards
6
Coulomb (C)
The unit of electric charge.
New cards
7
Proton
A positively charged subatomic particle found in the nucleus of an atom.
New cards
8
Electron
A negatively charged subatomic particle that orbits the nucleus of an atom.
New cards
9
Neutron
A subatomic particle with no electric charge that is found in the nucleus of an atom.
New cards
10
Elementary Charge (e)
The smallest unit of electric charge, approximately 1.6 × 10−19 C.
New cards
11
Conductors
Materials that allow the transfer of electrons freely from one object to another.
New cards
12
Insulators
Materials that do not allow the transfer of electrons.
New cards
13
Charging by Conduction
A charging mechanism where two in-contact objects allow movement of charged particles from one object to another.
New cards
14
Charging by Friction
A charging mechanism where electrons are rubbed from one object to another.
New cards
15
Charging by Induction
A complex charging mechanism where a charged object is brought close to a neutral object, causing the latter to become charged.
New cards
16
Law of Conservation of Charges
States that the sum of electric charges in any closed system is conserved.
New cards
17
Coulomb’s Law
States that the electric force between two objects is directly proportional to the product of the quantities of their charges and inversely proportional to the square of the distance between them.
New cards
18
Electric Force
The push or pull exerted upon an object due to interactions with another charged object.
New cards
19
Conversion of Charge
Conversion factors for electric charge: 1 mC = 1 × 10−3 C, 1 µC = 1 × 10−6 C, 1 nC = 1 × 10−9 C, 1 pC = 1 × 10−12 C.
