Direct current is defined as - CORRECT ANSWER - the flow of electrons in
one direction throughout a circuit with constant voltage and current
Faraday's Law - CORRECT 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 - CORRECT ANSWER - applying resistance
Current flows from - CORRECT ANSWER - negative to positive
Atoms - CORRECT ANSWER - represent the smallest elements that exist in
nature
Atoms are made up of - CORRECT ANSWER - protons, neutrons and
electrons
Nucleaus - CORRECT ANSWER - center of the atom
Electrons travel - CORRECT ANSWER - at the speed of light
Protons - CORRECT ANSWER - positively charged subatomic particles
Protons contain - CORRECT ANSWER - a positive electrical potential
,Protons positive charge - CORRECT ANSWER - affect the orbits of the
electrons
Neutrons are - CORRECT ANSWER - neutral subatomic particles
Neutrons are not involved - CORRECT ANSWER - in the conduction of
electricity
Electron's charge - CORRECT ANSWER - is negative
The speed of rotation combined with electrical potential - CORRECT
ANSWER - keeps the electrons in their orbits
The attraction of opposite charges - CORRECT ANSWER - holds the electron
in its orbit
Conductors - CORRECT 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 - CORRECT ANSWER - make up the atomic number for
the element
During conductance an extra valence electron - CORRECT ANSWER - flows
into the next atoms valance orbit
Good conductors - CORRECT ANSWER - Only those elements that dont hang
on to their valence electrons
Good Insulators - CORRECT ANSWER - Elements that don't give up valance
electrons no matter what force is applied
,lators - CORRECT ANSWER - a material or device used to prevent the
passage of heat, electricity or sound from one medium to another
Examples of insulators - CORRECT ANSWER - Glass, Mica, Silica
Air - CORRECT ANSWER - can be a good insulator but will spark when
enough electrical force is applied
Static Electricity - CORRECT ANSWER - an electrical charge that may be
built up on a non-conductive surface by friction
Static electricity serves - CORRECT ANSWER - no useful purpose in aviation
and cost millions of dollars in damage every year
Voltage - CORRECT ANSWER - electric potential energy per unit charge
measured in joules per coulomb

Coluomb is equal to - CORRECT ANSWER - 6.28 billion-billion electrons
Coluomb is the - CORRECT ANSWER - actual count of electrons in a unit of
measure
Joule - CORRECT ANSWER - amount of electrons in a suspended state as
compared to some electrons in an adjacent part of the circuit
Electromotive Force - CORRECT ANSWER - is the force required to move an
electron measured in volts
, EMF - CORRECT ANSWER - is the force required to cause one amp of the
current of flow through one ohm of reistance
Mechanical, Chemical, Friction - CORRECT ANSWER - three methods used
to generate EMF
Volt - CORRECT ANSWER - basic unit of measure of electrical pressure
A Volt is that amount of force - CORRECT ANSWER - required to cause on
amp of current to flow through one ohm of resistance
E is the symbol for - CORRECT ANSWER - volts
Current is - CORRECT ANSWER - the flow of electricity that pass a given
point in a specific amount of time
I is the symbol for - CORRECT ANSWER - amps
Amps - CORRECT ANSWER - unit of measure used to express the flow of
electrons
Current flows - CORRECT ANSWER - from a negative electrical potential to
a positive one
Resistance is - CORRECT ANSWER - electrical opposition to the current flow
in a conductor
Resistance does what - CORRECT ANSWER - opposed or slows down
another force, drops, voltage and consumes power
