Ampere ( A, amp, amperage) - Correct Answers ✅• 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 - Correct Answers ✅• 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 converts the energy into
electrical form
• Aircraft storage batteries are generally rated at 12 or 24 volts
Capacitor - Correct Answers ✅• Electrical device used to store charge
and energy in the form of an electrostatic field
• A capacitor is a device made of two parallel conductors separated by
an insulator
Conductor - Correct Answers ✅• 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.

2026)
Coulomb - Correct Answers ✅• Basic unit of electrical quantity.
• A coulomb is equal to 6.28 billion - billion electrons (6.28 x 10 to the
18th)
Current - Correct Answers ✅• The flow of electrons through a
conductor is known as current flow.
• The rate of current flow is measured in amperes.
Direct Current (DC) - Correct Answers ✅• A flow of electrons in one
direction throughout an electric circuit with constant voltage and
current.
• Direct current is caused by a constant difference of potential, both
negative and positive.
Electron - Correct Answers ✅• 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.
EMF (electromotive force) - Correct Answers ✅• The force that causes
electrons to flow through a conductor.
• This force is abbreviated e.m.f.
• The unit of measurement for eletromotive force is the volt.

• In mathematical problems voltage is expressed by the letter "E".
Farad - Correct Answers ✅• Basic unit of capacitance
• One farad holds one coulomb under a pressure of one volt.
Henry (H) - Correct Answers ✅• Basic unit of measurement for
inductance of an electrical coil
• One (1) henry is the inductance of a coil when a change of current of
one (1) ampere per second induces an e.m.f. of one (1) volt
• In mathematical problems inductance is expressed by the symbol "L".
Inductor - Correct Answers ✅• Coil or other device used to introduce
inductance into a circuit.
• An inductor is a winding, or coiling, of multiple turns of wire
Insulator - Correct Answers ✅• Material or device used to prevent the
passage of heat, electricity, or sound from one medium to another.
Left hand rule - Correct Answers ✅• Refers to electrical
• This rule is for determining the direction of movement of a current -
carrying conductor in a magnetic field

Magnetic Permeability - Correct Answers ✅• Measure of ease that
lines of flux travel through a material
Magnetism - Correct Answers ✅• Ability of a magnet to attract certain
materials containing iron and to influence electrons
• Magnetism is the principle way to effectively produce AC electricity
Metric Prefixes - Correct Answers ✅• Measurements relating or using
the metric system of measurement
Neutron - Correct Answers ✅• Neutral subatomic particles that exist
within the nucleus of all atoms
• Neutrons are not involved in the conduction of electricity
Ohm - Correct Answers ✅• Unit of electrical opposition to the flow of
current
• A circuit has one ohm of resistance when it limits the flow of current to
one amp under a voltage pressure of one volt
Ohm's Law - Correct Answers ✅• Ohm's Law states "the amount of
current flowing in a circuit is directly proportional to the circuit voltage
and inversely proportional to the circuit resistance"
• A plain language statement for Ohm's Law is; One volt causes one
ampere to flow through a resistance of one ohm.
