Introduction

This spreadsheet calculates the most common and basic electrical engineering formulas.

These are:

  1. Single phase power in kVA
  2. Three-phase power in kVA
  3. Single phase current in Amps
  4. Three-phase current in Amps
  5. Dissipated power in Watts
  6. Inductance in Henries
  7. Impedance in Ohms
  8. Resistance in Ohms

Spreadsheet is pretty easy to use, blue-text cells can be modified by user, and green-text cells represent the result.

    Hi there

    the formula on this sheet for single phase current calculation is incorrect. it should be 1000xkva/Volts. Just wanted to give a heads up
