QUETSIONS AND ANSWERS
Ampere (A, amp, amperage) - ....ANSWER ...-Unit of measurement used to
express the flow of electrons (electrical current). One ampere is a rate of flow of
one coulomb (6.28 billion - billion electrons) passing a given point in an electrical
circuit per second. In mathematical problems amperage is expressed by the letter
"I".
Battery - ....ANSWER ...-A device consisting of a number of primary voltaic
cells (cells that cannot be recharged) or secondary cells (cells that can be recharged)
connected in series to obtain a desired DC voltage. A battery stores chemical
energy and makes the energy available in the electrical form. Aircraft storage
batteries are generally rated at 12 or 24 volts.
Capacitor - ....ANSWER ...-Electrical component used to store electrical
energy in the form of an electrostatic field.
A capacitor is a device made of two parallel conductors separated by an insulator.

, Conductor - ....ANSWER ...-Common building block of electrical circuits
that easily permits the movement of electrons from an electrical source to a load
and back to the electrical source with a minimum of resistance.
A conductor's resistance depends on such factors as cross sectional area, length,
temperature, and conductor material.
Coulomb - ....ANSWER ...-Basic unit of electrical quantity.
A coulomb is equal to 6.28 billion - billion electrons (6.28 X 10 to the 18th).
Current - ....ANSWER ...-The flow of electrons through a conductor is
known as current flow.
The rate of current flow is measured in amperes.
Direct Current - ....ANSWER ...-Flow of electrons in one direction
throughout a circuit with constant voltage and current.
Direct current is caused by a constant difference of potential, both negative and
positive.
Electron - ....ANSWER ...-Negatively charged subatomic particles that are
located and travel around (orbit) the nucleus in an imaginary sphere or shell at the
speed of light (186,000 miles/second).
Electrons are involved in the conduction of electricity.
