60 Watt bulb draws about .5 amps (per hour). amps = watts / volts.
60 watts = 120 volts * .5 amps
My small battery is rated at 14.4 Ah (Amps per hour). Therefor it can power a 60 watt bulb for 28 hours: 14.4 Ah / .5 amps = 28 h
How many amps does a 60 watt bulb draw?
Answer:
I = W/E. Divide watts by volts. Since household wiring is basically 110 volts.

About 1/2 amp.
The simple way to do this is to divide the RATED wattage by the RATED voltage (120v in most cases). Then if your actual voltage is lower than 120v, your amps will be slightly below 1/2 amp. If your actual voltage is higher than 120v, your amps will be slightly higher than 1/2 amp. At 110v you get about .46 amps.
