iPhone and iPad Software to Calculate Resistance and Voltage Drop
Need to calculate the electrical resistance or voltage drop of a wire or cable? Wire Calc can do this, and more.
Enter in the length of the wire (using English or Metric) units and the gauge, select the type of wire (Copper or Aluminum) and WireCalc computes the resistance. Enter in the current, and the voltage drop is also computed.
There is also a table of all wire gauges from 0000000 to 50, with the diameter, area and resistance listed, for quick lookup.
The iPad version offers several additional features:
