Watts measure power and are the same regardless of voltage; they are calculated using the formula ( \text{Watts} = \text{Volts} \times \text{Amps} ). Therefore, if you have a specific power requirement, the current (amps) will differ based on the voltage. For example, a device that uses 120 watts will require 10 amps at 12 volts, but only 1 amp at 120 volts. Thus, while the wattage remains constant, the current varies with voltage.

How many watts is a 240 volt 20 amp fuse rated for with 12 gauge wire?
4800
What size of 12v transformer will run 600watts?
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.
How many watts can you put on a light switch?
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.
What will be out put wattage on convertion of 200 watt 12 volt DC to AC through inverter?
About 180 watts assuming a 90% conversion efficiency.
What is more powerful 1000 watts or 12 amps?
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.
