Electrical Formulas
Understanding the relationship between power, current, and voltage
DC (Direct Current)
Power (Watts) = Voltage (Volts) × Current (Amps)
Current (Amps) = Power (Watts) ÷ Voltage (Volts)
Used in batteries, solar panels, and automotive systems
AC Single Phase
Power (Watts) = Voltage (Volts) × Current (Amps) × Power Factor
Current (Amps) = Power (Watts) ÷ (Voltage (Volts) × Power Factor)
Used in residential and light commercial applications
AC Three Phase
Power (Watts) = Voltage (Volts) × Current (Amps) × Power Factor × √3
Current (Amps) = Power (Watts) ÷ (Voltage (Volts) × Power Factor × √3)
Used in industrial and heavy commercial applications
