The work done by a 100-watt light bulb when lit for 30 seconds can be calculated using the formula work = power x time. Power = 100 watts, Time = 30 seconds. Work = 100 watts × 30 seconds = 3000 joules.
The power of the light bulb is 100 watts since 1 watt is equal to 1 joule per second.
26.25 Joules per second
The 60 watts on the bulb indicates the power or energy consumption of the light bulb. It tells you how much electricity the bulb consumes to produce light, helping you to choose the right bulb for your lighting needs and to ensure you are using the appropriate wattage for your fixture to prevent damage.
The energy given off by a 100 W bulb in 4 hours can be calculated using the formula: Energy = Power x Time. Thus, Energy = 100 W x 4 hours = 400 Wh, or 0.4 kWh.

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.
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.
The work done by a 100-watt light bulb when lit for 30 seconds can be calculated using the formula work = power x time. Power = 100 watts, Time = 30 seconds. Work = 100 watts × 30 seconds = 3000 joules.
Almost twice as much as 100 is almost twice 60.
The power of the light bulb is 100 watts since 1 watt is equal to 1 joule per second.

The bulb is marked with the power (watts) and the voltage. Divide the watts by the volts and you have the amps.
The power output of a candle flame can vary, but it typically ranges from 5 to 80 watts. This can be influenced by factors such as the size of the candle, the type of wax, and the environmental conditions.
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.
40 watts of consumed power. The light output may be greater with one compared to the other, but wattage alone does not give us that information. Electric heaters, for example, consume 1500 watts of power and produce almost no visible light.Check the Lumen's. That is where the difference is.Current draw and light output.A 60 watt bulb uses 60 watts of electricity (i.e. it converts 60 joules of energy per second), a 100 watt bulb converts 100 joules per second. Electrical power is measured in watts. Since a 60 watt bulb pulls less energy to it than a 100 watt bulb the 60 watt bulb will not be as bright.Resistance.Just in the amount of power used and the brightness of the bulb. The 60 watt bulb might be a bit smaller.
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.
