P & M'S  Ohms Law V=IR Calculator.

 

Please feel free to download our Ohms Law  Spreadsheet Calculator. It was written using Microsoft Excel. As an added bonus it also includes the formula for calculating parallel resistor values. Regretfully like most things, although we believe the spreadsheet to be accurate you must accept any liability resulting from its use.

To simplify its usage unlike the track resistance spreadsheet, this one runs a small amount of Visual basic code in the background. To fully allow all functions, macros will need to be enabled. Although the sheet runs protected and locked, no password has been set.
