Amps * Volts = Watts Amps * 12 = 600 600/12 = Amps = 50 amps You would need a reserve capacity, so I'd go somewhere between 60 or 100 Amp rated transformer. Transformers are rated in volt-amps which is usually calculated the same as watts. But the term "watts" technically does not apply to transformers. So you need a 600 volt-amp transformer or, as Redbeard has suggested, you need an 800 or 1000 volt-amp transformer. That's a lot of amps for a 12 volt system so I recommend you double check your requirements. You will need a #2 gauge wire if your requirements are correct.
If we assume that you are using a common 15 Amp lighting circuit and switch and using 120 volts to power the bulbs then you need to keep the wattage at 80% of 15 amp worse case or 12 amps. Watts = amps x volts for standard incandescent bulbs. 12 x 120 = 1440 watts.
About 180 watts assuming a 90% conversion efficiency.
Watts = Amps x Volts x Power FactorYou can't answer your question because watts and amps are two different things. Watts is a measure of power and amps measures current flow.Additional informationPower factor refers to the efficiency of an electrical device. Power factors can have a value of between 0 and 1, with 1 representing perfect efficiency of an electric motor or similar device. In most applications, power factor is ignored and assumed to be 1. Using the above formula, you can see that 12 amps at 1 volt would be only 12 watts, while 12 amps at 120 volts would be 1440 watts.Given this information, you should be able to calculate the answer in your circumstance.
Watts = amps x volts. Something pulling 10 amps at 12 volts is 120 watts
Your electric bill is computed in kilowatt-hours. This is a measure of power over a period of time, which is a combination of volts and amps. Amperage at 240v would be half that of 120v, but obviously the voltage is double. So the net watts are the same. As a result, your net kilowatt-hours will be the same whether you use 120v or 240v.
On a 12 volt system the 80 watts draws 6.7 amp and the 120 watts draws 10 amps.
12 Amps x 12 volts = 1200 watts 1200 watts / by 120 volts = 10 amps at 120 volts Answer is 10 amp hours
Volts * Amps = Watts 12 Volt * 2 amp = 24 Watts
It's sometimes possible to use the secondary as the primary in transformers as long as you keep the overall power (wattage) the same or lower, and the AC frequency the same. ex. A 12 volt AC @ 10 Amp transformer (120 watts), will only yield 120v AC @ 1 Amp (120 watts)
The same number as 250 oranges is apples. A watt is a volt times an ampere.
12 Volts DC
12 volt systems are not measured in watts...... doofus
No, the battery is DC not AC.
To power ten 12 volt 10 watt lights, you would need a transformer with a total output of at least 120 volts and 100 watts.
On a 12-volt system 1.6 amps is 12x1.6 watts, 19.2 watts
