I am trying to measure current coming out of a wind generator and am having difficulties knowing/understanding exactly what I need to measure that current. My understanding is that I need to place a "precision resistor" in series with the wind generator and then using my cFP-AI-110 I can measure the voltage across the precision resistor and calculate the current. My problem is that I am expecting currents of up to 40 amps (@ 12V). And with that type of current, I'd burn up any typically resistor. So two questions:1. Is my theory correct in what I need to do to measure the current?2. Can anyone suggest a "precision resistor" that is capable of taking 480W and doesn't cost a fortune?Thank you for your time,Trevor
