How many volts does a flashlight need to make it work?
The answer is governed by the size of the flashlight. Count the amount of batteries that go into the flashlight and then multiply by 1.5 and this will give you the voltage of the flashlight. For NiCd and NiMH rechargeable batteries multiply by 1.3 volts.
Is sj cord rated for 300 volts to be used for 480 volt?
No. The voltage rating needs to be 600 volts for 480 volt power.
Which consumes more power 480 volts or 240 volts?
Volts isn't power. Volts times amps is power, also known as watts. Thus 480 volts at 2 amps consumes 960 watts, which is the same power usage of 240 volts at 4 amps or 120 volts at 8 Amps.

it's volts and not watts that the question needs to be asking. But the PS3 slim, which uses the least power needs more than 220 watts and it also needs power for the TV
How many volts does a flashlight need to operate?
I do not know working volts of other brands flashlights. Imalent flashlights are wotked from 2.8v to 9v.
What type of electricity does a flashlight use?
Usually, a flashlight will use either 3 or 6 volts DC, depending on how many batteries it takes.. The fact that it's a battery defines that it will be Direct Current (DC). Each battery is 1.5 nominal voltage, so: If a flashlight holds 2 batteries, it is (1.5 volts) x 2 = 3.0 volts. If a flashlight holds 4 batteries, then it is (1.5 v) (4) = 6 v. Now, I'm not sure on a 4-battery flashlight, if they are circuited separately somehow (I imagine they are, cause I've never had to decide between 3 or 6 volts when buying replacement lamps).
How many volts does a mechanical flashlight produce?
It honestly depends on the type of flash light.
How much electricity does a mall use?

Does battery size matter in a flashlight?
The size of that battery can increase weight, but the size can improve burn time and brightness. Bigger batteries generally supply more power. If the volts are increased this increases the capacity for a brighter bulb. If the amps are increased this increases the burn time of the flashlight.
How many volts are required to run a car?
12 volts
Why are batteries placed in a flashlight the positive terminal of one is connected to the negative terminal of the next?
Because they are connected in series. Lets say you have a flashlight that holds 2 D cell batteries. Each battery puts out 1.5 volts. Connect them in series and together they put out 3 volts. The flashlight is designed to run on 3 volts. A electronic device that uses 4 AA batteries is using 6 volts even though each battery is only putting out 1.5 volts. Connected in series you add to the voltage with the addition of each new battery.
