Pride in Craftsmanship

Enter any two known values and click "Calculate" to find the other two valuesVoltage (E) = Current (I) * Resistance (R) Power (watts) = Current Squared (I^2) * Resistance (R) Power = I*E = E^2 / R

Voltage (E) = Current (I) * Resistance (R) Power (watts) = Current Squared (I^2) * Resistance (R) Power = I*E = E^2 / R

Example:

A 60 watt light bulb operating on 120 volts AC.

The calculator should return 0.5 Amps (I) and 240 Ohms (R).

Click the Reset button before doing any other calculations or the calculator will use values from the previous calculation giving incorrect results.
