The basic gas law that describes the relationship between the temperature and the volume of a gas. Charles’s law states that if the pressure of the gas is held constant and its absolute temperature is increased, the volume of the gas will also increase.

The basic gas turbine engine consisting of the compressor, diffuser, combustor, and turbine. The gas generator, also called the core engine, is the part of a turbine engine that produces the hot, high-velocity gases. The gas generator does not include the inlet duct, fan section, free power turbines, or the tail pipe.

The basic measure of work in the English absolute system. One foot-poundal is the amount of work done when one poundal of force causes a movement of one foot in the direction of its application. One foot-poundal is equal to 0.0421 joule. The difference between a foot-pound and a foot-poundal is that foot-pounds use a measure of weight, and foot-poundals use a measure of mass.

The basic unit of apparent power in an AC circuit. A volt-amp is the product of the circuit voltage and all of the current, regardless of its phase. A volt-amp differs from a watt in that a watt is a measure of true power and is the product of the circuit voltage and only that current in phase with it.

The basic unit of capacitance. One farad is the amount of capacitance that allows a charge of one coulomb to be stored under a pressure of one volt.
The farad is too large for most practical circuits, so the microfarad (one millionth of a farad) and the picofarad (one millionth of a millionth of a farad) are the most generally used values of capacitance.

The basic unit of electrical pressure. One volt is the amount of electrical pressure needed to force one ampere of current through a resistance of one ohm. One volt is also the amount of electrical pressure drop that occurs when a current of one ampere produces one watt of power.

The basic unit of electrical work. One watt-hour is the amount of work done when one watt of power is used for one hour. One watt-hour is equal to 3,600 joules of work.

The basic unit of inductance. One henry, H, is the amount of inductance needed to produce an electromotive force of one volt, when the current in the inductor changes at the rate of one ampere per second.

The basic unit of length measurement in the metric system. One meter is equal to one ten-millionth of the distance between the equator and the earth’s north pole. The length of the standard meter is marked on a special bar of platinum alloy deposited in Paris, France.
One meter is equal to 1,650,763.73 wavelengths of the orange light emitted when an electric arc passes through krypton gas. One meter is also equal to 39.37 inches, and in the metric system the meter can be changed into millimeters, centimeters, and kilometers by dividing or multiplying by units of ten.

The basic unit of magnetic flux. One weber is the amount of magnetic flux in one turn of wire needed to produce one volt of electrical pressure, when the current flowing through the wire is reduced evenly at the rate of one ampere per second.
