The problems of electricity two light bulbs of 100 watt and one 60 watt both operation in a 220V circuit. Which bulb has the higher resistance and which bulb carries the greater current?
A 100 watt 220 volt light bulb (or anything consuming 100 watts on 220 volts) draws 100/220, or .45 Amps. It will also have about 220²/100, or 484 ohms resistance. A 60 watt 220 volt light bulb (or anything consuming 60 watts on 220 volts) draws 60/220, or .27 Amps. It will also have about 220²/60, or 807 ohms resistance.
Is 12 volt is enough for a 100 watt light bulb?
12 volts is enough for a 12-volt 100-watt light bulb. It would not be enough for a 120-volt or 240-volt bulb.
How many amps in a small table lamp?
A 120 volt table lamp with a 75 watt bulb will pull 0.625 amps. With a 100 watt bulb it will pull 0.833 amps. And with a modern fluorescent 13 watt bulb it will pull 0.108 amps.
Why does a 100-watt lamp glow brighter than a 25-watt lamp?
because it has more watts
What size cable to use on a 50 watt lamp?
16 AWG is plenty large enough for a 50 or 100 watt lamp.
How much does it cost to run a 240 volt 100 watt fluorescent lamp for 8 hours?
800 watthours, = 0,8 kWH, over here about 10-20 eurocents I guess.
How you check amp draw on compressor?
Divide the power rating (in watts) by the voltage (in volts). So if you use a 100 watt light bulb in a typical 110 volt lamp then it will draw 100/110 = .91 amps of current. Or plug a 1500 watt electric heater into a 110 volt wall socket and it will draw 1500/110 = 13.6 amps of current.
Does a 220 volt 100 watt cost less to operate than a 110 volt with the same bulbs?
no.
How many watts of lighting is required in a 15' x 10' room?
'Lighting', or the amount of light is not measured in watts. A 'watt' is a unit of power, measurement of current drawn. Most 100 watt/110 volt lamps initially produce 1690 lumens (a 'lumen' is the measure of the total "amount" of visible light emitted by a source). A 15 foot by 10 foot room is not very big, and one or two 100 watt incandescent lamps on a ceiling light fixture on a 120 volt service can light it adequately. I mention "110 volt" as in parts of the world with 220 mains these numbers change. As the voltage is doubled, the watts required would halve for the same amount of light. In other words, all other things being equal, a 50 watt 220 volt lamp should use the same amount of power, producing the same amount of light as a 100 watt 110 volt lamp.
What is the rate at which a 100-Watt incandescent lamp radiate heat?
About 100 Joules per second.
How many 100 watt bulbs can a 110 volt on 100foot line?
17
What size wire needed to power 100 watt bulb?
In a floor lamp or table lamp a #16 wire is what you need.
