How many kilowatts does a energy saving light bulb use?
Energy-saving bulbs use much less than 1 kilowatt and most of them use less than 40 watts which is 0.04 kilowatts. A 20 watt bulb uses 1 kilowatt-hour of energy if run for 50 hours.
Do household appliances use electrical energy at different rates?
Absolutely! the rate that energy is used at is called the power. Electrical energy in the home is measured in kilowatt-hours, which is the energy used by a 1-kilowatt device in one hour. If you take a low-power device such as a 20-watt lamp, that takes 50 hours to use one kilowatt-hour because 20 watts is 0.020 kilowatts of power, and 20 x 0.050 is 1.
How much eletrical energy in kilowatt hours would a 60.0 w light build use in 60.0 days if left on steadily?
In one day, 60x24 watt hours or 1.44 kWh. In 60 days, 86.4 kWh.
How much electrical energy is used by a 75 W laptop that is operating for 12 minutes?
Any device that uses 75 watts will use 75 watt hours of electricity in one hour. In 12 minutes, 1/5th of an hour, it will use 75/5 or 15 watt hours of electricity. This is the same as .015 kilowatt hours of electricity.
How much energy do flies use when flying?
It depends on the insect.
What type of energy does a wind up toy use?
Potential energy stored in a spring => kinetic energy of a toy
What energy does a toy car use?
siren
What kind of energy was use to move the toy car?
Mechanical Energy
How much energy does a 75kW motor use?
Multiply 75 kW by T hours of use = 75T kWh, which is how much energy the motor uses.
What kind of energy does the toy car use possess when placed on top of a piece of wood?
potetial energy
How much electrical energy does a 40 W light bulb use if it is on for 12 hours?
40w=.04kWh.04*12 hours=.48 kWh
How could we use kilowat hours?
A kilowatt hour (kWh) is a measure of how much energy you're using.It is simply a unit of measurement that equals the amount of energy you would use if you kept a 1,000 watt appliance running for an hour.Energy(in kilowatt-hours) = power in kilowatts × time in hours.
How much electricity does the average person use in a day hour wise?
How much electrical energy does the average person use in a day . . . In the UK the figure is about 16 kilowatt hours.
How much energy does a 100 watt light bulb use if it is left on all day?
100watts x 24 hours
What is a toy that an infant wouldn't get much use out of?
bike, racecar/truck, ball, video game, toy gun.
Does a PS3 waste a lot of energy?
I have a ps2 and i use it for about 3 hours, for a ps3 it use the same amount of energy for about 2 hours (thats like having an old tv on for 2 hours) so i guess you should play it for about 2 hours and it will not use too much energy! The PS2 uses 8.3 volts DC and far less power than a PS3 but both connect to TV sets. The question of whether playing a PS3 is a waste of energy could be applied to the TV just as easily.
How much eletrical energy energy in kilowat hours would 60 w light bulb use un 60 sdays if left on steadily?
60 days is 24x60 hours, so the energy used is 60x24x60 watt-hours, 86400 watt-hours or 86.4 kilowatt-hours or units. If it is a 60-watt incandescent bulb it could be replaced by a 12 watt low-energy bulb, and in the same time that would use only 17.3 units, saving 69 units costing about £10.
