In physics, power is the rate at which energy is transferred, used, or transformed. The unit of power is the joule per second (J/s), known as the watt (in honor of James Watt, the eighteenth-century developer of the steam engine). For example, the rate at which a light bulb transforms electrical energy into heat and light is measured in watts-the more wattage, the more power, or equivalently the more electrical energy is used per unit time.

In Watts. One Watt is equal to 1 Ampere (Amp, A, or I, a measure of current) flowing through 1 Ohm (R, a measure of resistance).

Power in watts = current in amps multiplied by resistance.

Power is *measured* using a meter in series with the electrical circuit, or with an Amp Clamp which is an non-contact meter which is clamped around a wire in the electrical circuit.

Power consumed is measured in amperes?

Power consumption is measured in many different ways.Power is usually measured in WattsVoltage usually in VoltsResistance in Ohmsand Current (or flow rate) in AmpsGoogle for "Ohms Law"AnswerYou do not 'consume' power. Power is the rate at which work is done.


How do you make voltage?

Power (P) = Voltage (V) x Amperage (I) Written as P=VxI or to find Voltage V=P/I Voltage is measured in Volts (V) Amperage is measured in Amperes (Amps or A) Power is measured in Watts (W)


What is the standard unit of power using ohm's law?

Ohm's Law has nothing whatsoever to do with power. Power is measured in watts.


What does conversion of electrical power to mechanical power mean?

There is no such thing as 'electrical power' or 'mechanical power' or, in fact, any other sort of power. Power is simply a rate -the rate of doing work. In SI, power is measured in watts. An obsolete unit of power is a horsepower. Although, in the Unites States, the power of an engine is usually measured in horsepower, elsewhere it is measured in watts (or, more usually, kilowatts).So, when an engineer describes converting electrical power to mechanical power, what he actually means is the rate of converting electrical energy to mechanical energy.


How you convert the value of single phase power to value of 3 phase power?

Electric power is measured in watts. It does not matter if it is single phase or three phase. All things being equal, for the same load, the power measured in a single phase circuit or a three phase circuit, will be the same.
