Useful Formulas

Formulas For Electrical Motors:

E = Volts HP = Horsepower PF = Power Factor (decimal)
EFF = Efficiency (decimal) I = Amperes

Formulas For Electrical Circuits:

To Find:	Direct Current	Single Phase	Three Phase
Amperes	Watts Volts	Watts Volts x Power Factor	Watts 1.732 x Volts x Power Factor
	--------------------	Volts x Amperes Amperes	1.732 x Volts x Amperes
Watts	Volts x Amperes	Volts x Amperes x Power Factor	1.732 x Volts x Amperes x Power Factor

OHMS Law	Capacitance in Microfarads at 60 HZ.
Ohms = Volts/Amps (R=E/I) Amps = Volts/Ohms (I=E/R) Volts = Amps x Ohms (E=IR)	Capacitance = 2650 x Amperes Volts Capacitance = 2.65 x kVAR (Volts) squared
