Fill in any two of the empty boxes below and press the "Calculate" button, and corresponding values will appear in the remaining two boxes. Be sure to reset all boxes to 0 before each new calculation.

Voltage (E) = Amps (I) × Ohms (R)
Power (Watts) = Amps² × Ohms (R)
Power = Amps (I) × Voltage (E) = Voltage² (E²) ÷ Ohms (R)

Volts (E)	Amps (I)	Ohms (R)	Power (Watts)
