you can always less less wattage. for safety, never use more wattage recommended due to fire hazard.
Almost twice as much as 100 is almost twice 60.
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
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.
Yes.
yes the bulb will actually last longer
power difference
1 watt = 1 Joule/sec 60 watts x 900 sec = 54 000 Joule 100 watts x 500 sec = 50 000 Joule So you use less electrical energy using 100 watt light bulb for 500 seconds.
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.
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.
Watts is Watts and has no relation to time. w=v*a (west Virginia varsity). A 60 watt light bulb is 60 watts regardless of how long it is on. Watt hours would be what PG&E bills you for.
100
Those numbers describe the power used by the two bulbs, in other words how many joules of electrical energy they use per second. The 100 watt bulb uses 40 watts more.
