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 calculate the amp hours used by a 13 watt bulb, divide the wattage by the voltage of the power source. For example, if the bulb is connected to a 120V power source, the current drawn would be 13W/120V = 0.1083 amps. This means the bulb would use 0.1083 amp hours for every hour it is on.

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 would a 150 watt bulb draw in a 120v circuit?
1 amp
How many 60 watt bulbs can a 15 amp handle?
A 15 amp circuit can handle approximately 8-10 60 watt bulbs. Each 60 watt bulb draws 0.5 amps of current, so you divide the circuit's amp rating (15 amps) by the current draw per bulb (0.5 amps) to get the approximate number of bulbs it can handle.
How many 25 amp bulbs fits 105 watt transformer?
Approximately 4 bulbs would fit a 105 watt transformer, as each 25-amp bulb consumes around 26.25 watts.
Can you use a 250 watt bulb with a 15 amp switch?
Yes, you can use a 250 watt bulb with a 15 amp switch. The switch is rated for up to 15 amps, which is more than enough to handle the power of a 250 watt bulb. Just make sure that the wiring and other components in the circuit can also handle the load.
What size circuit breaker is needed for a 300 watt bulb?
A 300 watt bulb requires a circuit breaker of at least 2.5 amps. This can be determined by dividing the power (300 watts) by the voltage (120 volts). However, considering normal breaker sizes, a 5 amp breaker would be sufficient for a 300 watt bulb.
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.
How many amps does a 5 watt 12 volt bulb draw?
To calculate the amperage, you can use Ohm's Law formula: Amperage (A) = Power (W) / Voltage (V). In this case, for a 5 watt bulb at 12 volts, the amperage drawn would be 0.42 amps (5W / 12V = 0.42A).
How many amps would a 150 watt bulb draw in a 120v circuit?
1 amp
Can you use a 250 watt bulb with a 15 amp switch?
Yes, you can use a 250 watt bulb with a 15 amp switch. The switch is rated for up to 15 amps, which is more than enough to handle the power of a 250 watt bulb. Just make sure that the wiring and other components in the circuit can also handle the load.
What is the current of a 60 watt bulb connetcted to a 120 V power source?
.5 amp
What size circuit breaker is needed for a 300 watt bulb?
A 300 watt bulb requires a circuit breaker of at least 2.5 amps. This can be determined by dividing the power (300 watts) by the voltage (120 volts). However, considering normal breaker sizes, a 5 amp breaker would be sufficient for a 300 watt bulb.
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.
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?
Approximately 4 bulbs would fit a 105 watt transformer, as each 25-amp bulb consumes around 26.25 watts.
What amp fuse do you use for a 100 watt bulb?
Fuses or breakers are used to protect the conductor to the load. A #14 wire conductor is rated for 15 amps. Most home circuitry is done with #14 wire. The minimum size breaker in an electrical panel is 15 amp so it looks like a 15 amp fuse or breaker can be used for a 100 watt light bulb.
