Electrical Formulas

 

 

 

 

Ohm's Law

 

Ohms =

Volts

Amperes

 

 

Amperes =

Volts

Ohms

 

 

 

 

Volts =

Amperes x Ohms

 

 

 

 

 

 

Power

 

Watts

Amperes x Volts

 

 

 

 

Amperes =

Watts

Volts

 

 

 

 

HP =

Volts x Amperes x Efficiency

746

 

 

 

 

Power Factor =

            Watts              

Amperes x Volts

 

 

 

 

3-Phase Kilowatts =

Volts x Amperes x Power Factor x 1.732

746

 

 

 

 

3-Phase Amperes =

746 x HP

1.732 x Volts x Efficiency x Power Factor

 

 

 

 

3-phase Volt-Amperes =

Volts x Amperes x 1.732

 

 

 

 

Single-Phase Kilowatts =

Volts x Amperes x Power Factor

1000

 

 

 

 

Single-Phase Amperes =

746 x HP

Volts x Efficiency x Power Factor
