Answers
Direct current is defined as - Answer -the flow of electrons in one direction
throughout a circuit with constant voltage and current
Faraday's Law - Answer -current will flow in a circuit provided there is electrical
difference in potential and there is a path for it to flow
Loads slow current by - Answer -applying resistance
Current flows from - Answer -negative to positive
Atoms - Answer -represent the smallest elements that exist in nature
Atoms are made up of - Answer -protons, neutrons and electrons
Nucleaus - Answer -center of the atom
Electrons travel - Answer -at the speed of light
Protons - Answer -positively charged subatomic particles
Protons contain - Answer -a positive electrical potential

,Neutrons are - Answer -neutral subatomic particles
Neutrons are not involved - Answer -in the conduction of electricity
Electron's charge - Answer -is negative
The speed of rotation combined with electrical potential - Answer -keeps the
electrons in their orbits
The attraction of opposite charges - Answer -holds the electron in its orbit
Conductors - Answer -easily permit the movement of electrons from an electrical
source to a load and back to the electrical source with a minimum of resistance
First two inner orbits - Answer -make up the atomic number for the element
During conductance an extra valence electron - Answer -flows into the next atoms
valance orbit
Good conductors - Answer -Only those elements that dont hang on to their valence
electrons
Good Insulators - Answer -Elements that don't give up valance electrons no matter
what force is applied
lators - Answer -a material or device used to prevent the passage of heat, electricity
or sound from one medium to another

,Examples of insulators - Answer -Glass, Mica, Silica
Air - Answer -can be a good insulator but will spark when enough electrical force
is applied
Static Electricity - Answer -an electrical charge that may be built up on a non-
conductive surface by friction
Static electricity serves - Answer -no useful purpose in aviation and cost millions
of dollars in damage every year

coulomb
Coulomb - Answer -basic unit of electrical quantiy
Coluomb is equal to - Answer -6.28 billion-billion electrons
Coluomb is the - Answer -actual count of electrons in a unit of measure
Joule - Answer -amount of electrons in a suspended state as compared to some
electrons in an adjacent part of the circuit
Electromotive Force - Answer -is the force required to move an electron measured
in volts

, EMF - Answer -is the force required to cause one amp of the current of flow
through one ohm of reistance
Mechanical, Chemical, Friction - Answer -three methods used to generate EMF
Volt - Answer -basic unit of measure of electrical pressure
A Volt is that amount of force - Answer -required to cause on amp of current to
flow through one ohm of resistance
E is the symbol for - Answer -volts
Current is - Answer -the flow of electricity that pass a given point in a specific
amount of time
I is the symbol for - Answer -amps
Amps - Answer -unit of measure used to express the flow of electrons
Current flows - Answer -from a negative electrical potential to a positive one
Resistance is - Answer -electrical opposition to the current flow in a conductor
Resistance does what - Answer -opposed or slows down another force, drops,
voltage and consumes power
First rule of resistance - Answer -current will take the path of less resistance
Zig zag line - Answer -symbol of a resistor in an electrical schematic
