Questions and CORRECT Answers
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 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
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
First rule of resistance - CORRECT ANSWER✔✔- current will take the path of less
resistance
Zig zag line - CORRECT ANSWER✔✔- symbol of a resistor in an electrical schematic
Resistance is measured - CORRECT ANSWER✔✔- in Ohms and uses the omega symbol
One ohm - CORRECT ANSWER✔✔- limits the flow of current to one amp under a voltage
pressure of one volt
Ohms law states - CORRECT ANSWER✔✔- the amount of current flowing in a circuit is
directly proportional to the circuit voltage and inversely proportional to the circuit resistance
