What thermal energy is supplied by the heater in 10swhen the power is 1440w?
Since power is defined as energy/time, if you solve for energy, you get:energy = power x timeIf the time is in seconds and the power in watts, the energy is in joules.
What is more powerful for a vacuum cleaner motor a 12 amp motor or a 110 watt motor?
A 110 watt motor is equal to a 1 amp motor... Versus a 12 amp motor, the 12 is more powerful. You've probably confused 110 watts with volts, as a 1 amp motor could not be used in a vacuum (it's too small).Basically the amount of power is dependant on the amps the motor uses. You only have the spec on 1 motor so we can't answer your question. All vacuum motors are 110 volt.You are trying to compare Apples and Oranges.Amps or Amperage is a measure of electrical current.Watts is a measure of electrical power.When dealing with single phase power, which is most common in residences, the two are related by the following formula:Watts (W) = Volts (V) x Amps (A)Further we can be certain that the voltage is 120V since we are talking about a vacuum cleaner that would plug into a standard 120V household outlet.A motor drawing 12 amps at 120V will produce 1440W under ideal conditions.You can now compare apples to apples. 1440W vs 110W, however all this tells you is that 12amp device generates more power.It dose not conclude that it provides more suction. For this you need to consider the efficiency (eff) of the devices.1440W x eff = suction power110W x eff = suction power
How do you find the power rating of something in kilowatts?
Actually the NEC says that the load on a branch circuit can only be 80% of the breaker size since Some appliances use a more energy to start up. so to be legal, you could only have a 1440W load on a 15 amp circuit, and 2880W with a 240 v 15 amp breaker.Another Answer You really should be asking how you can estimate ENERGY (not 'power') consumption, based upon a wattage rating. The term, 'wattage', is a slang term for 'power', which is expressed in watts. Power is simply a rate, the rate at which energy is being consumed, and energy (for the purpose of billing, at least) is expressed in kilowatt hours.So if you know the power ('wattage') of your load, then you must ensure that it is expressed in kilowatts and, then, multiply it by the number of hours that the load is operating. This will then tell you how much energy has been consumed over that period, expressed in kilowatt hours.
