LED: Light-Emitting Diode. A semi-conductor diode that efficiently converts
electric signals into light, and thus glows when current passes through it. In
microwave ovens, LEDs are generally used for control panel displays and
indicators.
LOAD: An object or device that consumes electrical energy, and thus changes
the energy into another form. Food products change microwave energy into heat
energy.
MEG OHM: One million ohms.
MICRO: A prefix meaning one-millionth.
MICROFARAD: One millionth of a farad; abbreviated MFD.
MICROPROCESSOR: A microprocessor incorporates various computer
functions such as memory, calculation, data processing, and control into a tiny
silicone chip. The microprocessor receives input and generates output signals in
a sequence of logic, which is either externally programmed or internally
preprogrammed.
MILLI: A prefix meaning 1/1000.
MILLIWATT: 1/1000 of a watt of electricity.
MODULATION/DEMODULATION: Modulation is the ability to impress
intelligence upon a transmission medium. A transmission medium may be
described as radio waves, light or infrared beams, wire lines, sound, or other
communication systems. The characteristics (intelligence) of one waveform are
impressed onto a second waveform by varying the frequency, amplitude, phase,
or other characteristics of the second waveform. Demodulation is the removal or
recovery of the intelligence from the medium.
MOSFET: Metal oxide semiconductor field-effect transistor.
NEGATIVE CHARGE: An electrical medium which has an excess of electrons,
thus having the ability to repel electrons.
NEGATIVE TEMPERATURE COEFFICIENT: A factor that expresses the
amount of reduction in the value of a quantity relative to ambient temperature.
For example, a given decrease in a resistance for each degree of increase in
temperature.
OHM: The basic unit of resistance. One volt will cause one ampere of current to
flow through one ohm of resistance.
