How many watts in a 100 amp 110 volt electrical service?

The formula you are looking for is W = E x I. Watts = Volts x Amps.


Which type of light bulbs use ΒΌ of the energy used by incandescent bulbs?

Incandescent bulbs use 75-100 watts. Fluorescent bulbs use around 10 watts. LED bulbs usually use 1 watt.


Does a 220 volt 100 watt cost less to operate than a 110 volt with the same bulbs?

no.


How many 100 watt lights per breaker?

I would use no more 14 100watt bulbs on a 15 amp circuit or 19 bulbs on a 20 amp circuit. You can calculate this by taking 80% of circuit amperage I.E 12 amps or 16 amps and then multiply by circuit voltage(120) to get 1440 watts and 1920 watts. Then take these values divided by bulb wattage(100 watts) to get 14.4 bulbs and 19.2 bulbs. Then round down for partial bulbs to get 14 bulbs and 19 bulbs.


How many watts does a light use?

Electric lights that use from 0.02 watts to 50,000 watts have been manufactured. The CFLs, fluorescent tubes, and incandescent bulbs in your house probably operate in the range of 20-100 watts.


Does it cost more to run four equals 25watt bulbs than one 100 watt bulb?

100 watts is 100 watts no matter how you add it up.


Power consumed by two 100watts bulbs in series?

100 watt, 110 volt on 110 volt supply? Assuming this is correct, power = voltage squared divided by resistance; two identical bulbs will result in the resistance doubling, so the total power used will be 1/2 the normal amount used by a single bulb - 50 watts.


How many volts does a 12 volt 100 amp alternator produce?

This will still only produce 12 volts. It will produce 1200 watts. watts is the result of Volts times Amps.


How many amps does it take to light 100 watt light bulb?

Watts = Amps * Volts100 watts = x amps * 120 volts100 watts / 120 volts = ~.83 ampsWhen lighted, a 100 watt 120 volt bulb takes 0.83 amps on a 120 volt supply (100 / 120 = .833)However, an incandescent bulb may take ten times it's operating current for an instant as the filament heats up. That's why bulbs often burn out just as they are switched on - the high current and the sudden temperature change stress weak points in the filament.


What does the difference between a watts and a 100-watts light bulb describe?

Those numbers describe the power used by the two bulbs, in other words how many joules of electrical energy they use per second. The 100 watt bulb uses 40 watts more.
