Unit of electrical power required to do work at the rate of one joule per second. One watt of power is expended when one ampere of direct current flows through a resistance of one ohm. In an AC circuit, true power is the product of effective volts and effective amperes, multiplied by the power factor.
Maximum power a device can safely handle continously.
Unit of electrical work, equal to a power of one watt being absorbed for one hour.
Instrument used to measure electric power in watts.
Electric, electromagnetic, acoustic, mechanical or other form whose physical activity rises and falls or advances and retreats periodically as it travels through some medium.
Shape of a wave.
Rectangular or circular pipe used to guide electromagnetic waves at microfrequencies.
(l) Distance between two points of corresponding phase and is equal to waveform velocity divided by frequency.
(Wb) Unit of magnetic flux. One weber is the amount of flux that when linked with a single turn of wire for an interval of one second will induce an electromotive force of one volt.
Secondary cell using a liquid as an electrolyte.
Term used in soldering to describe the condition that occurs when the metals being soldered are hot enough to melt the solder so it flowes over the surface.
Four arm bridge circuit used to measure resistance, inductance or capacitance.
Also called "broadband amplifier." Amplifier with a flat response over a wide range of frequencies.
Oscillator that uses an RC low-pass filter and an RC high-pass filter to set the frequncy of oscillations.
One or more turns of a conductor wound in the form of a coil.
Single solid or stranded group of conductors having a low resistance to current flow. Used to make connections between circuits or points in a circuit.
American wire gauge (AWG) is a system of numerical designations of wire diameters.
Method of making a connection by wrapping wire around a rectangular pin.
Term describing radio communication that requires no wired between two communicating points.
Resistor in which the resistive element is a length of high resistance wire or ribbon usually nichrome wound onto an insulating form.
Large loudspeaker designed primarily to reproduce low frequency audio signals.
Work is done any time energy is transformed from one type to another. The amount of work done is dependent on the amount of energy transformed.
