Electrical Formulas

on Wednesday, 7 December 2011



E      =  Voltage
I       =  Amps
PF    =  Power Factor
EFF  =  Efficiency
HP    =  Horsepower










Note:-
            Direct current formulas do not use (PF,2, or 1.73)

         -  Single phase formulas do not use (2 or 1.73)
         -  Two phase - four wire formulas do not use (1.73)
         -  Three phase formulas do not use (2)
         -  *For three-wire,two phase circuit the current in the common conductor is 1.41 times that in
              either of the other two conductors.

Note:-
            For more detail how to use this table ask your lecturer or your electrical engineers
