Rate at which electrical energy is converted to another type of energy?

The rate at which an appliance takes energy from the electrical outlet and spins
the electric meter is the "power" shown on the data label, usually on the back
or the bottom of the appliance.
The rate at which it actually converts the energy into the form required to do its
job is also a "power" figure. This one is always less than the power taken from
the wall outlet, and is not always stated or marked on the appliance.
A couple of cases where it is clearly stated:
-- Microwave Oven: " 600 Watts of Cooking Power "
The microwave oven is using perhaps 1,500 to 2,000 watts from the electric company,
converting some of it into radio waves (with less than 100% efficiency), and delivering
600 watts of microwave radiation to the cooking chamber.
-- Blow Drier: " 1,250 Watts of Drying Power "
The blow drier is using perhaps 1,500 watts from the electric company, and
delivering useful energy at the rate of 1,250 watts, in form of a hot coil and
a strong little fan motor to blow air across the coil.
But on an electric stove, furnace, blender, food processor, fan, telephone, TV,
computer, vacuum, washer, dryer, etc., you can find the power consumption
marked somewhere on it, but it's not clear exactly where that power goes.

How do you convert mechanical power to electric power?
Electrical Power equation: P = I x V (Electrical power = Current x Potential Difference) Hence if one has a Current in Amps (A) and a Potential Difference in Volts (V), these two values multiplied together give the size of the electrical power, P in Watts. 1 Watt is also equivalent to 1 Joule per second. Hence the units Watts maybe replaced by J/s or Js-1. Also, Using Ohms Law V = I x R (Potential difference = Current x Resistance) The electrical power equation maybe re-written: P = I x I x R = I2 x R = I2R (using V = I x R) or P = (V/R) x V = V2 / R (using I = V/R)
What is electric power?
Electric power is defined as the rate at which electrical energy is transferred by an electric circuit.Power is energy over time. For example electrical energy is watts and watts are usually measured by the hour by the utility company and the unit of power is a kilowatt hourAnswerThere is really no such thing as 'electric power', despite the term being widely used in everyday life. Power is simply a rate, the rate of doing work, or the rate of heat transfer. Work is done whenever one form of energy is converted into another form, so power applies to the all forms of energy conversion, as well as to heat transfer.The above answer is completely incorrect to say that electrical 'energy' is expressed in watts, and that 'watts are measured by the hour'. The watt is the unit of power, while energy is expressed in joules. The answer is also incorrect to say that the unit of power is the kilowatt hour, as this is used by electricity utilities to measure energy consumption, not power! In other words, the kilowatt hour is an alternative unit for energy.
What do amps measure in a circuit?
Amperage or Amps is a measure of is the flow rate of electrical current that is available.
Electrical power is expressed in watts or?
Electrical power is expressed in watts or in jouls per secondAnother AnswerThere is no such thing as 'electrical power'. Power is simply a rate: the rate of doing work. Power can be measured in watts (in the SI system) or in horsepower (in the Imperial system). There is no reason why the power of a heater can't be measured in horsepower or the power of a car can't be measured in watts.
What is the meaning of TOD meter in electrical engineering?
60 minutes, 30 minutes or 15 minutes Time of Day (TOD) : Up to eight, seasonal, time of day rate registers for energy and demand Power factory : Recording of average monthly power factor.
The rate at which electrical energy in converted into other forms of energy?
This is expressed in watts.
The rate at which an electrical device converts energy from one form to another is called what?
The rate at which an electrical device converts energy from one form to another is called electrical power. The rate at which electrical energy is changed to another energy form electrical power.
What is the rate at witch electrical energy is converted to another type of energy?
That is called "power". The SI unit for power is the watt, which is equal to joules/second.
What is the rate at which electrical energy is converted to another type of energy?
The rate of energy transfer - any type of energy transfer, including this specific case - is called the power. The SI unit is the watt, which is equal to joules/second.
Is electric force the rate at which electrical energy is converted into other forms of energy?
No, the two are unrelated.
What is the rate at which an electrical device converts energy from to another?
power
What is the rate at which an electrical device converts energy from one to another?
power
What is electrical power and what is electrical energy how are they related?
Compare electrical "current" to a river of water-and any size from the smallest trickel to the largest river.Now comparitivly speaking static would be as a collected pool of water(electricity) that is doing nothing-being "static".Now if equating getting wet with getting "a shock" either way ,finger in the river-or finger in the pool you will get wet both ways-as long as your body is toching ground at the same time.
How is energy and power related?
Power is the rate at which energy is transferred from one object to another or converted from one form to another.
What is electric and is the rate at which electrical energy does work?
Power; its SI unit is watt. Please note that this is notspecifically an electrical unit; "power", and the unit "watt", is the rate of energy conversion, and can be used anywhere where energy is converted - whether "work" is involved, or some other (non-mechanical) energy.
The rate at which an electrical device converts energy from one form to another?
The rate of energy conversion - not just electrical energy, but any type of energy - is called POWER. The SI unit is the watt, which is equal to joules per second.
A 100 watt light bulb converts electrical energy into electromagnetic energy at a slower rate that a 40 watt light bulb?
The higher the wattage, the more electrical energy is being used. In a light bulb the electrical energy is converted to EM energy which appears in both visible and infrared parts of the spectrum, so the answer is no, it will be at a higher rate for a 100 watt bulb
