Electrical Flashcards
What is an atom?
The smallest particle that an element can be broken into
What is electricity?
The movement of atoms from one electron to another
Why do electrons keep moving in orbet
Electrons are all Negatively charges so they repel each other, but want to stay close to the protons
An ion is a?
Atom that is not balanced, either too many or too few electrons
The Equalization process is also known as?
The flow of electricity
What is equalization?
When ions exchange electrons in order to be balanced. AKA The flow of electricity
What is the maximum amount of “shells” around a single nucleous?
Seven
What is the outermost electron shell/ring called?
The Valence ring
Free electrons are?
When a valence ring has 1-3 electrons on it
What is a material with 1-3 electrons?
A conductor
Bound electrons are?
When a valence ring has 5 or more electrons in it
What is material with more than 5 electrons?
An insulator
What is a material with exactly 4 electrons in the valence ring
Semi conductor
What must happen for current to flow?
There must be an imbalance on excess electrons at one end of a circuit and a deficiency of electrons at the opposite end
What is conventional theory?
The flow of electricity moves from the positive to the negative charged ends of the circuit
What is Electron theory
States that electron flow moves from the negative to the positive
Do we use conventional or Electron theory in automotive
Conventional
What is an amperes
-Unit of measurement for current flow.
-Does the actual work in the circuit
What is a Volt?
-Unit to measure electrical pressure (think water pressure)
-Also known as electrical potential because it is always at the power source wether it is being used or not
What are OHMS
Unit used to measure resistance
What is a Watt
-The electrical unit for power, the capacity to do work
(Amps)(Volts)=Watts
