I'm using a multimeter to measure the ohms, amperes, and volts coming from the the Duemilanove's 5V pin. Connecting one probe of the multimeter to the 5V pin, and the other to the ground pin, the multimeter reports a resistance of 0.9kohms, 5V, and 0.55A. I convert 0.9kohms to 900ohms and plug the v…

Multimeter readings do not match math
