- Okay, I can visualize getting a cheap ammeter and connecting it between a battery post and cable to find out how much various things load my charging system. But you can't very well measure the draw

- Here are the formulas you requested: Power = P (expressed in Watts) Voltage = V (expressed in Volts) Amperes = A (expressed in Amps) Resistance = R (expressed in Ohms) P = VA V = AR A = R/V R = V/A

- Oops, Stuart is right! A = V/R In addition, Power can also be expressed as P = (V x V)/R

- Matt, Let's start with the last part first: 1) Watts = Volts X Amps 2) Amps = Watts/Volts 3) Volts = Amps X Resistance 4) Amps = Volts/Resistance Substituting 3 into 1, we have 5) Watts = Amps X Amps
