Sorry, I was just going hypothetically. If everything was 100% efficient and a device plugged into a home outlet drew 500w over 120v, then the amps would be 4.16. In theory, if the same device ran 500w over 120v on a 12v battery. What are the numbers for the voltage, amps, and watts coming...
Hello, I just came across this site when looking for some info. Not sure if this is a stupid question but I would like to know what the correlation between AC and DC power is when comparing one device. For example if i had a a device connected to 120vac and it drew 500w then the amps would be...
