They will use the same amount of power. A 100 watt bulb will use 100 watts. If a bulb is rated at 100 watts and is specified as a 120 volt bulb, if you apply the 120 volts, it will draw 0.83 amps. Volts times amps equals watts. If you have a bulb rated at 100 watts and is specified as 12 volts, if you apply the 12 volts, it will draw 8.3 amps.
its the same amount of electricity a watt is just a unit of work. V(Volts) x A(amps) = W(watts). you might want to take in the consideration of direct current and alternating current also if your planning on doing anything electrical.
The formula you are looking for is I = W/E where I is the current in amps, W (or P) is the power in watts and E is the potential difference in volts.
A worked-out solution
I = P/E = 50/240 = 0.208 A
With different ampere - electrical current
Watts are volts x amps, so amps are watts / volts
50/12 = 4.2 amps
50/240 = 0.2 amps
Same power(Watts), different voltages and different currents(amps)
If you want your bulbs to last longer then use 130 volt bulb on a 120 volt system. The light emitted by a 130 volt bulb, when comparing it to a 120 volt bulb, will be a bit dimmer.
Yes, for about .1 second, then it will blow the lamp. A 9v battery will however light three 3.5v lamps.
no it will burn the vacuum out too much voltage
36-volt bulbs are easily found, try Amazon.
The question is "use less of what?". If they are both the same wattage the 240 V light will use 1/2 the current of a 120 V light.
Any Pikachu I Used A Male One To Get Pichu With Volt Tackle, But You Can Get Volt Tackle With A Female.
Yes, you can easily use it. Just install it as you would any other 120 volt light fixture and change the bulb from a 240 volt bulb to a 120 volt bulb. It will work just fine.
Hook a 12 volt light to a 24 volt system and the light will burn out in seconds. You need a step-down voltage converter to do this.
depends on the size of 6 volt battery, if it's 4AAA might get 24 hours straight however if the 6 volt battery has a MAH (Milli amp hours) of say 75 then this case you might get 275 hours. much like the emergency back up light system in a warehouse, those are likely 6 volt

Yes, in fact that is what a rough service bulb is rated at. The bulb used on a 120 volt system will have a reduced wattage output as to what it would be on 130 volts.
Yes a 220 volt light bulb will run on a 120 volt circuit but at 1/4 of the wattage that the light bulb is rated at. A 100 watt light bulb on 220 would would be equal to a 25 watt light bult on 120 volt system.
Yes, for about .1 second, then it will blow the lamp. A 9v battery will however light three 3.5v lamps.
Cars do not have 120 volt batteries. They are 12 volt DC.
no it will burn the vacuum out too much voltage
7.4 volts.
About as much as 15 typical (60watt each) light bulbs together. Or expressed in horsepower: about 1.2Hp Mains volts and ampere: 230 volt at 3.91 ampere = 900watt 110 volt at 8.18 ampere = 900watt
