Handy conversion formulas

OHM'S LAW FORMULAS

Seems this guy named Ohm figured out some stuff....

  • Voltage = the Square Root of Power * Resistance
  • Voltage = Power / Current
  • Voltage = Current * Resistance
  • Resistance = Voltage / Current
  • Resistance = Power / Current squared
  • Resistance = Voltage squared / Power
  • Current = Voltage / Resistance
  • Current = the Square Root of Power / Resistance
  • Current = Power / Voltage
  • Power = Voltage * Current
  • Power = the Current squared * Resistance
  • Power = the Voltage squared / Resistance

HANDY CONVERSION FORMULAS

Converting Watts to Amps

The conversion of Watts to Amps is governed by the equation Amps = Watts/Volts

For example 12 watts/12 volts = 1 amp

Converting Amps to Watts

The conversion of Amps to Watts is governed by the equation Watts = Amps x Volts

For example 1 amp * 110 volts = 110 watts

Converting Watts to Volts

The conversion of Watts to Volts is governed by the equation Volts = Watts/Amps

For example 100 watts/10 amps = 10 volts

Converting Volts to Watts

The conversion of Volts to Watts is governed by the equation Watts = Amps x Volts

For example 1.5 amps * 12 volts = 18 watts

Converting Volts to Amps at fixed wattage

The conversion of Volts to Amps is governed by the equations Amps = Watts/Volts

For example 120 watts/110 volts = 1.09 amps

Converting Amps to Volts at fixed wattage

The conversion of Amps to Volts is governed by the equation Volts = Watts/Amps

For Example, 48 watts / 12 Amps = 4 Volts
