Seamonster, that was handy- In measuring electric power, neither the current in amperes nor the pressure in volts tells us the amount of power in a circuit at any moment. A combination of the two does tell us the answer very simply, because volts X amperes = watts. 3 volts x 120amps = 360 watts 6 volts x 60 amps = 360 watts 12 volts x 30 amps = 360 watts 60 volts x 6 amps = 360 watts 120 volts x 3 amps = 360 watts 360 volts x 1 amp = 360 watts * * a 1 hp motor is a 746 watt motor also <br />if you think about it in model train talk 1 1/2 watts would equal 1/500 th hp** Al
