The Electric Power in an AC Circuit Calculator will calculate the:

- Electric power in an AC circuit when the maximum current and driving frequency are known

**Calculator Settings:** The conducting wire of circuit is uniform and it has the same thickness everywhere; the source supplies AC current

The power of circuit as a function of time is W [Watt] |

Power of circuit as a function of time |
