How much energy does a lamp use?
well it depends on the type of lamp but it should say on the packaging
How much electrical energy is produced by a light bulb with the power ratings of 60w?
A lamp doesn't produce electrical energy; it utilises it. The power-rating of the lamp will tell you the rate at which that lamp uses expends energy at its rated voltage. For example, a 60-W lamp will expend energy at 60 joules per second.
How much energy is wasted on Christmas lights?
The power is specific to the lamp set.
How much power does a 250 watt hps light use an hour?
compare to different lamps mv lamp,hpsv lamps & cfl lamp these are how mush energy comsumed for 225w lamp
A 100-W light bulb is turned on it has an operating voltage of 120 V how much energy is used each second?
A lamp will only operate at its rated power when subject to its rated voltage. So, provided your lamp is operating at its rated voltage (120 V), it's power will be 100 W, which means its consuming energy at the rate of 100 J/s.At any other voltage, its operating power will change, and the rate at which it consumes energy will change too.
How much energy does a 20w CFL lamp use in 1hr?
energy = power * time = 20w * 1hr = 20 watthours or 0.02 kilowatthours
What is the advantage of having a brushed nickel floor lamp?
The advantage of having a brushed nickel floor lamp is that it is energy efficient. Another advantage of having this lamp is that it has a good finish and it does not take up much space in a room.
What is the rule for working out how much electricity you are wasting?
Energy input minus useful energy output. So if you were using a lamp you could work out how much energy was going in and how much was actually coming out in light. Then whatever's leftover is being wasted.
How long does cold water evaporate under a lamp?
a few days or weeks. It might even take months depending on how hot the lamp is and how much cold water you're trying to evaporate.
How much energy does a 250watt bulb use per hour How much energy does the average light bulb use per hour?
There are many factors that go into calculating the energy usage of a light bulb. The wattage printed on the lamp is only the energy use of the lamp when it is new. Depending on the kind of lamp he energy required to run it will increase as it ages. For example a Metal Halide lamp can use up to 50% more power in the last 20% of its life.Another factor is the ballast that may be required to run the lamp. Each ballast has a "ballast factor" which can increase or reduce the overall energy usage of the lamp. Many ballasts have a factor as high as 1.2 which would increase the energy consumption of the lamp to 300 watts.AnswerThe question is asking about energy, not power as per the previous answer. To find the energy consumed by a lamp, or any device come to that, multiply its power rating by the time for which it is used. So a 250-W lamp will use 250 W.h (watt hours) of energy in one hour, 500 W.h in two hours, and so on. Energy is more-commonly expressed in kilowatt hours, for the purpose of billing however, where 250 W.h corresponds to 0.25 kW.h, etcAnswer: In an hour it uses 250 watt-hours. The average bulb probably uses 20-60 watt-hours each hour.
How tp convert sound energy to light?
There is so much of noise around us, the horn, a guy whistling, a television drama in progression, kids playing and shouting. We certainly can't do much about such noise but to put a deaf ear. But a constructive mind has done something far beyond imagination. The energy from these sounds is actually captured to light up a LED lamp. All that is needed is a speaker that acts as a microphone and a lamp with LED lamp and a wire. The speaker absorbs the sounds present in the environment and the energy is then channeled into lighting up the LED lamp. some times you may have to amplify the electrical signal from the speaker then give to the led lamp.
How does a lamp change the energy that comes from the wall into energy that makes the room brighter?
both sound and light are forms of energy,so electricity is turned into light. the process? couldnt tell you but i do know that much.
