NATE CORE Study Guide Questions and Answers
Verified 100% Correct
Static Electricity - (answers)Electricity at rest. It is either positive or negative
charge, and if an object contains an equal amount of charge it is considered
uncharged
What can control static electricity? - (answers)raising the humidity
how can you remove excess humidity in an A/C system? - (answers)By slowing
down the blower speed. this allows air to have more contact time with the coil,
increasing the delta temperature across the coil and removing more humidity in
the process. do not slow the blower speed too much because this may cause
freezing.
current - (answers)refers to the flow of electrons through a conductor
current electricity - (answers)electricity in motion. current is the flow of electrons
through a conductor, like a wire, water or air.
What is EMF? - (answers)Electron motive force. It is created when the current
flow is in between a potential difference and flows from negative to positive.
What is a volt? - (answers)The force required to move one ampere through one
ohm of resistance.
, 2
How is rate of the current flow measured? - (answers)It is measured in
amperes(amps) and depends on the applied voltage.
What is ohm? - (answers)the amount of resistance in a circuit that allows one volt
to cause one ampere to flow through a circuit.
In a schematic circuit, what is the letter symbol for volts, amperes, and ohms? -
(answers)volts is E
amperes is I
ohms is R
what is the relationship that ohm's law expresses? - (answers)current is found to
be directly proportional to the applied voltage and inversely proportional to the
circuits resistance.
when is an electromagnet produced? - (answers)when an electric current flowing
through a wire produces a magnetic field around a wire the wire becomes an
electromagnet.
what are flux lines - (answers)they indicate the varying levels of force created by a
magnet that become stronger nearer to a magnetic pole and help create
movement in an alternating current.
which electrical components rely on the magnetic attraction/repulsion principle? -
(answers)some contactors and relays.
