2. Structure of an Atom
Proton - A positively charged molecule inside of
an atom.
Electron - A negatively charged molecule inside
of an atom.
Neutron - A non-charged particle inside of an
atom.
Nucleus - Center of the atom, usually the
‘heart’, if you will.
3. Ion and Ion Formation
● An ion is a charged atom.
● A positively charged ion will have fewer or
less amount of Neutrons.
● A negatively charged ion will have more
electrons than protons.
● They form by taking away or giving
electrons.
4. Law of Conservation of Charge
● If an electrical charge is created once
something is charged, it cannot be created
or destroyed.
7. Electrical PE
● Evectional repelling of 2 like charged
particles against each other.
● EPE= Electric Potential
Charge
8. Conductors
● These material atoms have electrons that
are loosely bound to their nuclei; these free
electrons conduct the electricity & the
disrupted electrons create a current.
Ex: Copper, Silver,
Aluminum,
Mercury,
Silver
9. Insulators
● These materials electrons are NOT free but
rather tightly bound to the nuclei; this makes
it impossible to create a flow of energy &
therefore they will not conduct & pass a
career along.
Ex: Rubber,
Porcelain, Glass
Wood,
10. Semiconductors
● These materials atoms fall into the mid-
range of conductivity since they possess few
electrons that are free to move.
Ex: Silicon and Germanium….
11. AC - DC
● An alternating current is an AC, which flows
in different directions inside of a circuit.
● A direct current is a DC, which flows in a
single direction inside of a circuit.
12. Ohm’s Law
● For each given circuit, there will be constant.
● C= V/R
14. Electrical Circuits
● Any system that allows electricity to flow
through it, like a conductor or
semiconductor.
15. Magnets
● An object with two repelling sides, positive
and negative, in which is repels what it
portrays.
● If you break a magnet, the resulting piece
broken down becomes a new magnet.
