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
,Protons positive charge Answer - affect the orbits of the electrons
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
Voltage Answer - electric potential energy per unit charge measured in joules
per 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
