Direct current is defined as - ANS the flow of electrons in one direction throughout a circuit
with constant voltage and current


Faraday's Law - ANS 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 - ANS applying resistance


Current flows from - ANS negative to positive


Atoms - ANS represent the smallest elements that exist in nature


Atoms are made up of - ANS protons, neutrons and electrons

,Protons - ANS positively charged subatomic particles


Protons contain - ANS a positive electrical potential


Protons positive charge - ANS affect the orbits of the electrons


Neutrons are - ANS neutral subatomic particles


Neutrons are not involved - ANS in the conduction of electricity


Electron's charge - ANS is negative


The speed of rotation combined with electrical potential - ANS keeps the electrons in their
orbits


The attraction of opposite charges - ANS holds the electron in its orbit


Conductors - ANS 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 - ANS make up the atomic number for the element


During conductance an extra valence electron - ANS flows into the next atoms valance orbit


Good conductors - ANS Only those elements that dont hang on to their valence electrons


Good Insulators - ANS Elements that don't give up valance electrons no matter what force is
applied

,lators - ANS a material or device used to prevent the passage of heat, electricity or sound
from one medium to another


Examples of insulators - ANS Glass, Mica, Silica


Air - ANS can be a good insulator but will spark when enough electrical force is applied


Static Electricity - ANS an electrical charge that may be built up on a non-conductive surface
by friction


Static electricity serves - ANS no useful purpose in aviation and cost millions of dollars in
damage every year


Voltage - ANS electric potential energy per unit charge measured in joules per coulomb


Coulomb - ANS basic unit of electrical quantiy


Coluomb is equal to - ANS 6.28 billion-billion electrons


Coluomb is the - ANS actual count of electrons in a unit of measure


Joule - ANS amount of electrons in a suspended state as compared to some electrons in an
adjacent part of the circuit


Electromotive Force - ANS is the force required to move an electron measured in volts


EMF - ANS is the force required to cause one amp of the current of flow through one ohm of
reistance

, Mechanical, Chemical, Friction - ANS three methods used to generate EMF


Volt - ANS basic unit of measure of electrical pressure


A Volt is that amount of force - ANS required to cause on amp of current to flow through one
ohm of resistance


E is the symbol for - ANS volts


Current is - ANS the flow of electricity that pass a given point in a specific amount of time


I is the symbol for - ANS amps


Amps - ANS unit of measure used to express the flow of electrons


Current flows - ANS from a negative electrical potential to a positive one


Resistance is - ANS electrical opposition to the current flow in a conductor


Resistance does what - ANS opposed or slows down another force, drops, voltage and
consumes power


First rule of resistance - ANS current will take the path of less resistance


Zig zag line - ANS symbol of a resistor in an electrical schematic


Resistance is measured - ANS in Ohms and uses the omega symbol
