How much work can a 500 watt electric mixer do in 2.50 minutes?
The work or energy in Joules is the power in watts times the number of second it runs for. So 500 watts for 150 seconds is 75,000 Joules.

The general answer is that the electric motor makes it go. Electricity is converted to mechanical energy by the motor, and the power is transferred through gears (to correct s…peed) and coupled to the mixing head or to the mixer blade shafts.
A watt is not typically used as a unit of measurement here. You may be asking for the number of watt-hours. Power is billed in kilowatt-hours (KWH). A 10 watt electric blanket… use 10 watt-hours per hour, so that would be 2.5 watt-hours in 15 minutes. Divide 2.5 watt-hours by 1000 to get KWH. Take the total kilowatt-hours and times that by your rate (for me 15 cents) to get the total cost for those 15 minutes ($0.000375 or almost free, far less than a penny)
Multiply the watts by the seconds: 500 x 300 = 150,000 Joules is the answer.
About 17 mph
If one kilowatt hour of electricity costs 9cents how much to run a 500 watt heat bulb 24 hours for 30 days?
500 watt bulb run for 1 hour = 500 watt/hours or 0.5 kilowatt/hours 0.5 x 24 x 30 = 360 kilowatt/hours 360 x 0.09 = $32.40
A Watt is a joule per second. So in a whole hour there are 360 seconds. 500 x 360 = 180. kilojoules in a whole day there are 8640 seconds. 500x 8640 = 4320 kilojoules…
There is no such unit as a 'watt per minute' or a 'kilowatt perhour'.
Well, it's an easy enough math problem, so I'm just going to tell you *how* to do it. 1 Watt = 1 Joule/second 5 minutes = 5*60 seconds Multiply so that the seconds cancel eac…h other out. This is simpler to just do with dimensional analysis than to try to evaluate it in separate steps.
If you use a 1200-watt hair dryer for 15 minutes and a 100-watt light bulb for one hour how much electricity did you use?
Work is the same as energy, equal to power times time. 500 wattsfor 2 minutes could be expressed as 1000 watt-minutes, but is moreconventionally expressed as 500x120 watt-seco…nds, otherwise knownas 60,000 Joules or 60 kJ.
If use a 1200 watt hair dryer for 15 minutes and a 100 watt light bulb for one hour how much electricity do you use?
1200 watts for 15 minutes = 300 watt-hours 100 watts for 1 hour = 100 watt-hours Total = 400 watt-hours = 0.4 kilowatt-hour of electrical energy
The sizing of the generator is dependant on the size of the electric motor driving the mixer.
In Pool Care and Cleaning
A 500-watt vacuum cleaner is plugged into a 120-volt outlet and used for 30 minutes How much current runs through the vacuum?
In this case 4.2 amps of current are running through the vacuum.
In Home Electricity
Watts is a measure of power. Watts is defined as volts x amps x power factor. The maximum value of power factor is 1 for a resistive load and decreases with various inductive …loads. Now electricity doesn't relate directly to wattage other than knowing how many amps are required for a given voltage. In a typical incandescent 100 watt light bulb you have 120 volts and about .83 amps.
In Math and Arithmetic
That depends upon the mixer and the speed. For example, a 600 watt mixer run at full speed for one hour will consume 0.6 kW-hours in one hour. It would consume 0.1 kW-hours in… 10 minutes. A 300 watt mixer run at full speed would use half that much, or 0.05 kW-hours in 10 minutes. Running the 300 watt mixer at half power would cut the power consumption in half again, to 0.025 kW-hours per 10 minutes.

P = I(current in amps) x V (voltage) in watts.
In Vacuum Cleaners
A 500-watt vacuum cleaner is plugged into a 120-volt outlet and used for 30 minutes. How much current does it use?
This machine will draw about 4.17 amps all the time while it isrunning. It will have used 250 watt-hours of electricity during its30-minute duty cycle.
