How many watts does a 12 volt battery produce?
A 12 volt 1ah (amp hour) battery is rated to put out 12 watts for 1 hour before it is fully discharged. Or it could do 24 watts for a half hour. A 12 volt 2ah battery can put out 24 watts for 1 hour or 48 watts for half an hour.
Can you use 12 volt battery 6 volt system?
Yes, you can use a 12-volt battery on a 6-volt battery. However, you will need to make some adjustments to the wiring system and perhaps the converter to get the best results. Note that if a Power Wheels car uses a 6-volt battery, chances are most of the electronic components are rated 6 volts.
How many volts does a 5 ton ac unit use?

Why does us use 110 volts?
After the dust settled, the U.S. electricity distribution industry agreed on 110 Volts AC as their standard. This was to quieten the idea that 220 volts were far too dangerous in the public mind. Thus Edison had his way with the numbers 110, but not with the letters DC.
Can you get 240 volt from 480 volt?
