Ohm's Law and Watt's Law Variables

E = Electromotive Force = Voltage

I = Impedance = Amperage

R = Resistance = Ohms

P = Power = Wattage

Formulas for Ohm's Law

E = I * R Volts = Amps * Resistance

I = E / R Amps = Volts / Resistance

R = E / I Resistance = Volts / Amps

Formulas for Watt's Law

P = I * E Power = Amps * Volts

I = P / E Amps = Power / Volts

E = P / I Volts = Power / Amps
