how can i convert that to amps?
Amps = unit of current = rate of change of charge.how can i convert that to amps?
Uh... hmm. This is true (as a simplification) in this case, but is not always true.They both stay constant and do not change with time.
Not neccessarily. Depends on the country.To find the amps, divide by the watts by 120.
