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.
A 60 watt light bulb uses 60 watts of power in a period of one hour or 60 watts in one minute or 60 watts in one second or 60 watts during any period of time.How much total energy a 60 watt light bulb "consumes", which is the amount of electricity that has to be paid-for, is measured in watt•hours (that's watts times hours). So a 60 watt bulb consumes 60 watt•hours in one hour, or 60 Wh x 24 hr/day = 1440 Wh per day.That is the same as 1.44 kilowatt•hours (kWh), so, if you look up what your electricity supplier charges for 1 kWh you can figure out how much it would cost you in money. If 1 kWh costs you 25 cents, then leaving a 60 watt light bulb switched on for 24 hours straight would cost you 1.44 kWh x 25¢/kWh = 36 cents.
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.
A 1,000 watt is 15,000 lumens. A 100 watt bulb is 1,500 lumens.
I kW = 1000 W 100 / 1000 = 0.1 So a 100 W bulb uses 0.1 kW For one hour that's 0.1 kWh
A watt is a measurement of electricity, usually pertaining to light. Light bulbs luminosity is graded by wattage, such as a 60 watt bulb, 100 watt bulb and so on. You would find a watt in a light bulb, to start.
That bulb is 100 watts or 0.1 kilowatts so it uses 0.1 kilowatt-hour of energy each hour, which costs about £0.015
Almost twice as much as 100 is almost twice 60.
The rhyming word for a 100-watt bulb is "dull."
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.
A 40 watt bulb is dimmer than a 100 watt bulb.

A 1,000 watt is 15,000 lumens. A 100 watt bulb is 1,500 lumens.

100
the highest light bulb is 100
Yes. It just won't be as bright.
I kW = 1000 W 100 / 1000 = 0.1 So a 100 W bulb uses 0.1 kW For one hour that's 0.1 kWh
