Unit - Power 14


  This base formula can be used in a different manner to calculate

   other factors.

             Rearrange the formula and you have

             Power = Current multiplied by Voltage

              Current = Power divided by Voltage

             Voltage = Power divided by Current




n       Power = Current Voltage and you get     P=IE

n      Current = Power / Voltage     I=PE

n      Voltage = Power / Current     E=PI
