You have to multiply the power times the time, to get energy. In this case, you get either 1 kilowatt-hour or 3,6 millions watt-seconds (joules).

The unit used to express power is called?
Power is expressed in Watts
What is the cost for the microwave if it used one day for 20 min?
Great question! It depends on the size. 20 minutes = 0.66 hours. Small: 800 watts/hour 264 watts in 20 minutes Medium: 1440 watts/hour 475 watts in 20 minutes Large: 2000 watts/hour 666 watts in 20 minutes To get an idea of how much this is, in terms of cost and in comparison with other appliances, you may want to check out the related link.
How many minutes are in a kilo minute?
The term killowat simply means 1000 watts. Watts are computed as volts times amps. A load of one killowat used for one hour consumes one killowat hour of energy. That would be 60 killowat minutes, however that measurement is seldom used.
How much power is used by a blender that operates on 120 V and 2 A?
240 Watts
Do 100 joules of work in 50 seconds and your power output is?
If one were to do one hundred Joules of work in five seconds, he/she would have a power output of 20 Watts.
What is killowatt?
Kilo- is used to denote a thousand of anything. Therefore a kilowatt means a thousand watts, which is a measure of power, electrical or mechanical.
The unit used to express power is called?
Power is expressed in Watts
What is the unit used to measure the power of a microwave?
Watts.
The SI you units used to describe power are?
Watts
What unit is used to express electrical power?
Electrical power is also measured in Watts.

How many kilowatt hours would be used if 1500 watt used for 10 minutes?
1500 watts = 1.5 kilowatts 10 minutes = 1/6 hours. So 1500 watts for 10 minutes = 1.5/6 = 0.25 kilowatt hours.
How many watts are in 600 volts?
You are confusing electrical potential (Volts) and power (Watts). The equation for power (watts) is P = VI where V is volts (a measure of electrical "pressure") and I is current in amperes (the rate of flow of electricity). If the system is 120V and the power used is 600W then the current used is 5A. If the system is 240V and the power used is 600W then the current used is 2.5A.
What label is used for power?
Watts measures power. It is abbreviated simply with a W. It is energy used (or work) over time. Thank you. So what does 1 lb = 4.45 N mean using the label used for power? If Watts measures power and is abbreviated with a W and is the label that is used for power, then what is the label used for Work?
How many minutes are in a kilo minute?
The term killowat simply means 1000 watts. Watts are computed as volts times amps. A load of one killowat used for one hour consumes one killowat hour of energy. That would be 60 killowat minutes, however that measurement is seldom used.
A microwave oven uses a 115 V ran for 15 minutes how much electrical energy would it use?
Not enough information. To get the amount of electrical energy, you need to multiply the power used (in Watts) by the time (in seconds). The power used is not equal to the voltage; it is volts x amperes. Look for a metal sticker that shows the electrical characteristics of the device; it should show the amount of Watts used. If it only shows Volts and Amperes, multiply both to get the amount of Watts. (Technically there is also a power factor, but that can often be ignored.)
What is watts and what is watts measured in?
Watts are used to measure electrical POWER. You can use the mnemonic CAROPWEV to remember this CA=CURRENT measured in AMPERES RO=RESISTANCE measured in OHMS PW=POWER in WATTS EV=ENERGY in VOLTS you can get power by multiplying the current by the voltage.
