Voltage X current (AMPS).

Watts is the unit describing amount of power per channel that the television can produce. On stereo sets, this is the amount of power for each speaker; on mono sets, this is the total amount produced by the television.

Measurement of amplifier power. Home amplifiers and receivers must be rated in watts per channel, or the amount of power the amp sends to each speaker.

The expression of the mechanical rate of work (power output) for a device, such as a cardiovascular machine.

A unit for measuring total electric power. A KiloWatt (kW) is 1000 Watts.

Measure of the rate of work done by electricity. Watts = volts x amps. One horsepower = approximately 746 watts.

The unit of power, symbol W

the unit of power. If large amounts of power are involved then megawatts (MW) are used.

A linear measure of optical power, usually expressed in milliwatts (mW), microwatts (*W) or nanowatts (nW).

An International System unit of power equal to one joule per second.

A measurement of electrical power equal to the amperage of a current times its voltage. Wattage provides a measurement of the amount of power required by a device or set of devices.

Unit of power used to rate amplifiers & speakers, not loudness or volume. See RMS.

A watt is a measurement of total electrical power. Volts x amps = watts.

The unit of measure of actual power. Watts are the product of volts times current.

Electrical power also expressed as ‘W' For example a 100W globe consumes 100 Watts of electrical power The W in Watt is always uppercased, because it is named after a person.

Total amount of electrical energy. Volts x Amps = Watts

Unit of measure for any kind of power e.g. RF, heat, etc.

per channel This is a measure of the power output of a system or loudspeakers. It can be quoted in a number of ways - see also RMS and Peak Power Output.

A rate of energy transfer, a measure of the amount of electricity used by a device.

Unit of measurement that represents the power output of an electric engine. 746 watts is equal to 1 horsepower.

A unit of electrical power equal to 1 joule per second. Lamps are rated in watts to indicate power consumption. Also see Nominal watts.

A unit of electrical power. Named after James Watt, a British inventor. 746 watts = 1 horsepower.

A measurement of energy, arrived at by multiplying the voltage by the amperage.
