The Joule's Law Calculator will calculate the:

- Output (useful) energy (heat energy for resistors) delivered by a circuit component
- Input (total) energy produced by the electric source of the circuit (battery)

**Calculator Settings:**

- Medium is considered as uniform.
- The wire is considered at the same thickness everywhere.
- Enter 0 [zero] when an input is not known, the Joule's Law Calculator will automatically select the appropriate Joule's Law formula to complete the calculations.

The useful energy delivered by the circuit component is J [Joule] |

The total energy produced by the source is J [Joule] |
