Power System Volts and amperes are measures of electricity. A volt is the unit of electric potential difference, or the size of the force that sends the electrons through a circuit. An ampere is the unit used to measure electric current. Current is a count of the number of electrons flowing through a circuit. One amp is the amount of current produced by a force of one volt acting through the resistance of one ohm. (An ohm is a way of measuring resistance.

Electrical Definitions Define Amps, Volts, Watts, Ground The main way electricity consumption is measured is with the unit “watt-hour”. A watt (W) is a measure of electrical power. Light bulbs are marked with a watt rating, such as 40 W, and so are appliances like air-blow heaters (around 1,000 W). In fact, most appliances have a compliance badge that will give you an indication of the amount of electrical power it needs to work.

Measuring Electricity The power consumption of small devices is usually measured in Watts, and the power consumption of larger devices is measured in kilowatts (kW), or 1,000 Watts. Electricity generation capacity is often measured in multiples of kilowatts, such as megawatts (MW) and gigawatts (GW).

watt Part of the Electronics glossary: The watt (abbreviated W) is the International System of Units' (SI) standard unit of power (energy per unit time), the equivalent of one joule per second.n radio-frequency (RF) circuits and systems, the calculation of powerbecomes more complex. This is because, at high frequencies, AC is affected not onlyby resistance, but by reactance. Inthese situations, no simple formulas exist for the calculation of power.

Electric power Electric power is transmitted on overhead lines like these, and also on underground high voltage cables. Electric power is the rate, per unit time, at which electrical energy is transferred by an electric circuit. The SI unit of power is the watt, one joule per second. Electric power is usually produced by electric generators, but can also be supplied by sources such as electric batteries. It is usually supplied to businesses and homes by the electric power industry through an electric power grid.

Power The standard metric unit of power is the Watt. As is implied by the equation for power, a unit of power is equivalent to a unit of work divided by a unit of time. Thus, a Watt is equivalent to a Joule/second. For historical reasons, the horsepower is occasionally used to describe the power delivered by a machine.
