Compute DC power P = V × I in watts from a supplied voltage and current. Using R, also compute P = V² / R or P = I² × R.

METHOD / LOCAL RUN
Compute P using one of three equivalent formulas: P (W) = V × I = V² / R = I² × R, depending on which two of V, I, and R the user supplies.
Boundary: DC, single-loop. No AC real/apparent power, no power factor.
The calculation or transformation runs in your browser using the values entered above. No input is sent to UtilityForge for this tool.

FAQ
No. The electrical power calculator runs entirely locally.
The workbench states the exact method behind every result — the formula or procedure this page runs — so you can verify the computation instead of trusting a black box.
No. This workbench runs in the page: Mode, Voltage (V), Current (A), Resistance (Ω) are read by the code your browser already downloaded, and UtilityForge receives neither the values nor the result.
