Assuming the lamps are plugged into a 60 volt outlet, the 40 W lamp has more resistance. This can be shown mathematically:
Resistance= V2/P=602/40=3600/40=90 ohms (40 Wlamp)
Resistance= V2/P=602/60=3600/60=60 ohms (60 Wlamp)
This shows that 40W lamp has more resistance than a 60W lamp.
Assuming the bulb operates at a standard voltage of 120V, you can use the formula P=V^2/R to calculate the resistance. Rearranging the formula, R = V^2/P, R = 120^2 / 60 = 240 ohms. The resistance of a 60 watt bulb operating at 120V is approximately 240 ohms.
Did you buy it in Europe or in North America ?
In North America, it's expecting to be powered by 120 volts.
In most of the rest of the world, it expects 240 volts.
120 volts, 60 watts:
P = E2 / R
R = E2 / P = (120)2 / 60 = 240 ohms
240 volts, 60 watts:
R = E2 / P = (240)2 / 60 = 960 ohms.
Yes, it consumes about 33% less provided both bulbs are of the same type. It consumes less because the current is less.
AnswerThe power of a lamp, in watts, is the rate at which it consumes energy -so, obviously, a 40-W lamp will consume less energy over a given period of time than a 60-W lamp -in the same way as you will travel less far at 40 km/h than you would at 60- km/h!
The 40 watt bulb will for sure, you can find this out using simple watts and ohms laws. P=VC and V=RC where P=power V=voltage R=resistance and C=current.

How can a 60 watt bulb use the same power as a 60 watt bulb can in a second?
A 60 watt bulb uses 60 watts of power continuously per second. It is consistent with the definition of power, which is the rate at which energy is consumed or produced. Therefore, a 60 watt bulb would use the same amount of power as another 60 watt bulb within the same timeframe of a second.
Can I use a 60 watt bulb in a 75 watt bulb ceiling fan?
Yes.
What size fluorescent bulb replaces a 60 watt incandescent bulb?
A 13-15 watt compact fluorescent bulb (CFL) or a 9-11 watt LED bulb is roughly equivalent to a 60 watt incandescent bulb in terms of light output.
What is the different between a 100 watt bulb and a 60 watt bulb?
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.
Does 660 watt socket use a 60 watt bulb?
Yes, a 660 watt socket can safely handle a 60 watt bulb. The wattage rating of a socket indicates the maximum amount of power it can handle, so a 60 watt bulb is well within the safe range for a 660 watt socket.
What does a light bulb have?
The resistance of a light bulb varies, depending on the type of bulb, the power rating, and the temperature. A typical incandescent 60 watt bulb, for instance has a cold resistance of about 30 ohms, and a hot resistance of about 240 ohms.
The problems of electricity two light bulbs of 100 watt and one 60 watt both operation in a 220V circuit. Which bulb has the higher resistance and which bulb carries the greater current?
A 100 watt 220 volt light bulb (or anything consuming 100 watts on 220 volts) draws 100/220, or .45 Amps. It will also have about 220²/100, or 484 ohms resistance. A 60 watt 220 volt light bulb (or anything consuming 60 watts on 220 volts) draws 60/220, or .27 Amps. It will also have about 220²/60, or 807 ohms resistance.

A 13-15 watt compact fluorescent bulb (CFL) or a 9-11 watt LED bulb is roughly equivalent to a 60 watt incandescent bulb in terms of light output.
Can you use a 130 volt 60 watt bulb in a socket that was made for a 110 volt 60 watt bulb?
yes the bulb will actually last longer
A 60-watt 120 volt lamp requires morecurrrent than a 40 watt 120 volt lamp?
Yes. A 60W bulb has a higher resistance than the 40W buld. The extra resistance requires more current to light up the bulb. The fillament then glows brighter.
For bulbs connected in series the high watt bulb has high resistance?
No, the highest wattage bulb will have the lowest resistance.
Will a 45 watt bulb work in a 60 watt housing?
Yes.
Which will last longer a 40 watt bulb or a 60 watt bulb?
They will last about the same period of time.
What is heat output of one 60 watt light bulb?
A 60 watt light bulb produces 60 watts of heat energy as a byproduct of generating light.
Is a watt a light bulb?
A 60 watt light bulb is a light bulb with 60 watts capacity. When talking about watts, you're talking about the power that is transferred from the appliance to the accessories. Therefore, the light bulb labeled "60 watts" takes 60 watts to light up. A 60 watt light bulb will not be as bright as a 120 watt light bulb.
