Top Answer

A 60 watt incandescent bulb using 120 Volts draws about one-half amp.

Watts = Volts x Amps (For a resistive load).

By Ohm's Law Volts = Current x Resistance so R = 120 V / .5 A = 240 Ohms.

Doing the same math for a 40 watt bulb you get 360 Ohms.

0On this calculation I am assuming that the light bulb is using a 120 volt source. Watts = Amps x Volts. Amps = Watts/Volts, 40/120 = .33 amps. R = Volts/Amps, 120/.33 = 363.6 ohms resistance in the 40 watt light bulb.

Electrically, a 10-watt bulb uses 75% less energy than a 40-watt bulb. For the same circuit voltage, let's say 120v, a 10-watt bulb would only draw 0.083 amperes, compared to 0.33 A for a 40-watt bulb. Light-output-wise, they may not have the same ratio of light output. If a 40-watt lightbulb provides 400 lumens of light, a 10-watt lightbulb that is more energy-efficient than the 40-watt bulb may produce more than 100 lumens which is greater than 1/4 of the light output of the 40-watt bulb. A 10-watt bulb that is less energy-efficient than the same 40-watt bulb would produce less than 100 lumens of light.

It will work, a 40 w bulb is a little brighter than a 34 w and it takes a little more electric power.

The higher the wattage the more you pay for power. So it costs more to operate a 120 watt bulb than it does a 100 or 40 watt bulb.

It isn't more, it is less if bulbs are of the same type.

the 40 watt bulb will glow brighter in series because it will consume less power.

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.

Because more energy goes through it, you pay more and you get more result.AnswerA 100-W lamp has a lower operating resistance than a 40-W lamp. Since power is equal to the voltage squared divided by the resistance, for a given voltage the power will be higher and its operating temperature (therefore brightness) will be higher.

60 watts. This means that the 40 watt bulb uses less electricity but it also produces less light.

It depends on the bulb and its efficiency. A typical 40 watt incandescent bulb puts out about 475 lumens.

An electrical watt is a measure of power. A 40 watt light bulb uses 40 watts of electrical power. It has a relative measure of twice the light output of a 20 watt bulb and one half the output of an 80 watt bulb. A 40 watt bulb uses 40 Joules of energy each second, or 40 watt-hours of energy each hour. In 1000 hours it uses 40 kilowatt-hours or Units of electrical energy.

If it is a 40 Watt bulb it converts energy at the rate of 40 Watts as long as it is switched on.

You want to compare the lumens of the bulbs.

A watt is 1 volt x 1 amp. Your question doesn't contain enough information. You would need to know the resistance of the bulb, which is related to the design.

They will last about the same period of time.

A 40 watt bulb is dimmer than a 100 watt bulb.

Technically speaking a bulb and a lamp are the same thing. You can use a 60 watt bulb in a fixture calling for a 40 watt bulb but I wouldn't. The lighting fixture may get to hot, melt and start a fire.

Possibly but its really never been proven. In my opinion I think it won't.

40 watt hours or .04 kWh

40 watt light bulb. This is obvious. Go do an experiment. -_-

no because it will be to little

looking for a 40 watt g bulb what is that?

It depends on the bulb. A 25 watt bulb uses 25 watts, a 40 watt uses 40 watts, a 60 watt bulb uses 60 watts, a 75 watt bulb uses 75 watts, a 100 watt bulb uses 100 watts, all the way up to a 500 watt bulb. Incandescent bulbs are about to cease to exist, so this answer is only good through the fall.

Yes you can as long as it doesnt have a a higher wattage or voltage

Because the filament of a 40-W lamp has a higher resistance than that of a 60-W lamp and, therefore, will experience a greater voltage drop -the lamp with the voltage drop closer to its rated voltage (in this case, the 40-W lamp) will be the brighter.Read more: Why_does_a_25_watt_bulb_glow_brighter_than_60_watt_in_a_series_circuit
