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.

ReneTo 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.
It depends.
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.
