The power of a light bulb that converts electrical energy at a rate of 100 joules per second is what?
100 joules/second = 100 watts.
Why is 60 watts written on the bulb?
It is probably a 60 watt bulb (believe it or not). Bulbs are rated in watts. A 100 watt bulb is brighter and consumes more power than a 60 watt bulb
Why is a 100 watt bulb brighter than a 25 watt bulb?
Because it takes more current and power and produces more light power. Running a 100 w lamp costs 4 times more than a 25 w lamp.
How much energy will a 100w light bulb convert to light and heat if it is left burning for 1hour?
Power = Energy/time 100W=Energy/360 Seconds Energy = 100/360 Energy ≈ 0.27 Joules
How much work does a 100-watt light bulb do when it is lit for 30 seconds?
3000 joules(J)
How many watts is a lighthouse light?
A standard lighthouse bulb is 1 million candle power. This is about 1000 watts. The standard household bulb is only about 60 to 100 watts.
How much are candle centerpieces for wedding?
$100 a set
How much energy does a nightlight use compared to a 100 watt bulb?
An incandescent nightlight bulb is either 4 watt or 7 watt. A 4 watt bulb uses 1/25th (0.04) the power of a 100 watt bulb. A 7 watt bulb uses 7/100th (0.07) the power of a 100 watt bulb. There are LED and other types of nightlights that use much less power than this. To find the energy total used multiply the power (in watts) by the total time the light is on (in hours) to get energy (in Wh). If you want kWh divide this by 1000 as a watt is 1/1000th of a kW.
How bright is an led bulb marked 100 lumen?
Brightness is measured in lumens so the bulb has a brightness of 100 lumens. The electrical power the bulb uses is measured in watts. The efficiency of a bulb is expressed in the number of lumens produced per watt of electric power.
How much more money will it cost if you use 100 watt bulb then a 60 watt bulb?
Almost twice as much as 100 is almost twice 60.
What equation would you use to calculate how much current in AMPs is required to achieve the full 100 to output from a volt bulb?
The bulb is marked with the power (watts) and the voltage. Divide the watts by the volts and you have the amps.
How much a hour does 100 watt bulb use at 15p?
A 100 w light bulb uses one tenth of a kilowatt of power, therefore in 1 hour it uses one tenth of a kilowatt-hour of energy, that is 0.1 units, or 1.5 p.
How much volts does a small light bulb need to be powered?
110 volts is what comes out of an average wall socket in America. A 100-watt bulb would be powered by 110 volts. You need to be more specific in your question to get a good answer. Small can't be measured.
What is the power output of a candle flame?
100 W .1 Kw
Does a candle create more pollution than a light bulb?
No. Burning 3 candles puts out slightly more CO2 than a 13 watt CFL bulb. However, The CFL bulb puts out about 24 times more light than 3 candles. In terms of a 100 watt incandescant lightbulb, it produces roughly the amount of light produced by 120 candles, however only produces about as much CO2 as 23 candles, so you could say it's about 5 times more efficient (in terms of pollution output) than a candle. A CFL bulb, then, is about 20 times more efficient than the candle.
What percentage is a 100 watt light bulb brighter than a 60 watt light bulb?
Original answer: Because it gives off more power. Updated answer: In general, because the 100-watt bulb produces more total light (lumens) because it also consumes more power than the 60-watt bulb. However, a 60-watt can produce more lumens than a 100-watt bulb, depending on the types of bulbs in question.
The power of a light bulb that converts electrical energy at a rate of 100 joules per second is what?
100 joules/second = 100 watts.
