A 13W bulb consumes 13W/110V=0.118 A.
If you use it for an hour, it consumes 0.118 Ah, for 2 hours 0.236 Ah, and so on..
Answer
Lamps don't use ampere hours, as this is simply a unit of measurement for electric charge. You probably mean 'watt hours' which is a measure of energy. A 13-W lamp will use 13 Wh for each hour it is used.

To get the Amps a 3 Watt bulb uses, divide the Watts by the Voltage.
Current (in Amps) = Watts/Voltage.
A 3 watt bulb operating on 3 volts would use 3/3 or 1 amp.
A 3 watt bulb operating on 9 volts would use 3/9 or one third of a amp.
A 3 watt bulb operating on 120 volts would use 3/120 or 0.025 amps or twenty five thousandths of an amp.
A 3 watt bulb operating on 240 volts would use 3/240 or 0.025 amps or one hundred and twenty-five ten-thousandths of an amp.

How many amps does a 5 watt 12 volt bulb draw?
1/2 amp.
How many amps would a 150 watt bulb draw in a 120v circuit?
1 amp
What minimum fuse rating is needed for a 12volt curcuit with a 36 watt bulb?
36 watt / 12 volt = 3 amp
How many amps does in a 60 watt bulb draw?
Without knowing the voltage, I can not tell you how many amps a 60 watt light uses. If you have a 12 volt system in a car, then a 60 watt light will pull 5 amps. If you have a 120 volt system in a house, then a 60 watt light will pull 1/2 amp. If you have a 240 volt system in an industrial building, then a 60 watt light will pull 1/4 amp.
Can you use a 250 watt bulb with a 15 amp switch?
A 15 amp switch can safely handle up to 1400 resistive watts.
How many amp hours does a 23 watt bulb use?
The formula for finding amperage is I = W/E. Amps = Watts/Volts. Without the value of the voltage to the bulb this question can not be answered.

What is the current of a 60 watt bulb connetcted to a 120 V power source?
.5 amp
Can you use a 250 watt bulb with a 15 amp switch?
A 15 amp switch can safely handle up to 1400 resistive watts.
How many watt does a 60 watt light bulb use if turn it on and off?
If it is an incandescent light bulb (Gives off heat too hot to touch) it consumes 60 Watts when on and 0 watts when Off. When on it draws about 1/2 amp at 120 VAC.
How long can a battery power a 44 watt light bulb?
To answer this question the amp hour rating of the battery is needed along with the voltage of the battery or bulb.
How many watt in an amp?
That depends on the voltage.
How long will a 1 watt bulb operate on a 1 amp hour battery?
Please give the voltage and Ah rating of the battery and voltage rating of bulb.
How many 25 amp bulbs fits 105 watt transformer?
To answer this question a voltage must be given. 25 amps drawn by a bulb seem to be on the high side.
