it varys from light bulb to light bulb.
The formula you are looking for is Watts = Amps x Volts.

Lamps use whatever voltage they are designed to run on. If the question as asking about the energy used, this is measured in watts. Watts are calculated as: W (watts) = V (volts) x I (amps) which is the product of the voltage and the current drawn.
If you mean the USA, there they use 120 volts / 60 Hz.
150-250 volts
Philips lamps in the USA have a minimum of 12 volts suggested. This can vary according to the lamps and bulbs used and also for the location of the lamp and its usage.
If all four lamps are identical, there will be an identical voltage drop on each. 3 volts / 4 lamps = 0.75 voltage drop at each light.

12 volts.
Light bulbs, called lamps, are run on 110 to 120 volts AC when they plug into household wiring. Other lamps use 1.5 volts, 3 volts, 4.5 volts or 6 volts DC when they are running off batteries in flashlights. Car lamps use 12 volts (though the actual car voltage is a bit more). Lamps have ratings that are specified by the manufacturers, and they have a given voltage rating based on their design. There are quite a few different lamps that come in a variety of voltage ratings.
Many lamps use electrical energy, but some lamps use chemical energy, for example a kerosene lamp or a candle.
A car battery has usually 12 volts.
How many volts for a 9 mag
An electrical device doesn't really "use" volts. The volts in a minute are the same as the volts in a second or in a day - since the voltage tends to remain fairly stable.
Most likely 12 volts if it is on a car. Some boats use 24 volts, or in the case of my boat 32 volts.
