Basic Electricity-In Hvac Questions And
Answers 100% Correct!!!
Alternating current (AC) - ANSWER✔✔ current that reverses its direction of flow
periodically. Reversals generally occur at regular intervals.
Ampere - ANSWER✔✔ The amount of current required to flow through a
resistance of one ohm with a pressure of one volt, measured with an ammeter.
Atom - ANSWER✔✔ the smallest part of an element that contains all the
properties of that element.
Compound - ANSWER✔✔ A substance that is a combination of atoms from at
least two different elements.
Conductor - ANSWER✔✔ A wire that is used for the path of electric flow. Most
electric conductors are copper or aluminum.
Current - ANSWER✔✔ Electrons flowing in an electric circuit, measured in
amperes.
Direct current - ANSWER✔✔ An electron flow in only one direction; used in the
industry only for special applications such as solid-state modules and electronic air
filters.
Electric energy - ANSWER✔✔ Energy that is produced by a movement of
electrons. The energy can be produced by chemical, light, thermal, or mechanical
means.
Electric power - ANSWER✔✔ The rate at which electricity is being used,
measured in watts.
Electric pressure - ANSWER✔✔ Another term used to refer to electromotive
force, potential difference, and voltage.
Electricity - ANSWER✔✔ Energy that is capable of producing and electron flow.
An unbalanced condition that results when an electron can be easily displaced from
an atom.
