Comprehensive Review, Practice Questions
& Rationales
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
Coulomb - correct answer-basic unit of electrical quantiy
, 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
