Watts and Amps are two separate things. Watts is a measure of Power and Amp (Ampere) is a measure of electrical current. Look at the following formulae. Formula 1: W=V x I where W is Watts, V is Volts and I is Amps. Formula 2: I=V/R where I is Amps, V is Volts and R is Resistance (in Ohms) Formula 2 can be written as V=IxR and if you put this into Formula 1 you get a third formula which is: Formula 3: W=IxIxR So Power W is proportional to Current I squared. Note that milliAmps are Amps/1000 Ray Ashmore, Helston
