Watts = Amps * Volts
100 watts = x amps * 120 volts
100 watts / 120 volts = ~.83 amps
When 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 amps do in a light bulb?
Take the wattage of the bulb and divide that by the voltage of the bulb. This will give the current the bulb draws. Amps are a measure of charge (electron) at an instant of time through a conductor. In an incandescent bulb the filament is heated by the current and the characteristics of the filament, usually tungsten, is that it gives off light when heated.
How many amps does a led light draw?
Depends on the size of the LED light and the voltage applied. An example is an LED 24 volt globe light that pulls 8 watts which draw 0.333333 amps. Take an LED 120 volt light bulb draws 12 watts and will pull 0.1 amps. The same bulb at 240 volts wil draw 0.05 amps. it really depends on the watts and voltage applied. An average would be about 0.1 amps.
How many philosophers does it take to change a light bulb?
Define "light bulb"
What is the amps from a small light bulb?
You just have to divide the watts by the voltage to find the amps. For example 60 watts on a 120 v system would take ½ amp.
How many potatoes does it take to change a light bulb?
You wouldn't use a potato to screw in a light bulb... if the glass in the light bulb breaks as you're removing it, you can use a potato to take the light bulb out.

How many amps does a 50 watt bulb use?
You just have to divide the watts by the voltage to find the amps. For example 60 watts on a 120 v system would take ½ amp.
