Calculation breakdown

Result interpretation
Solve electrical input power, current or supply voltage for DC and balanced AC loads

Only the result summary and canonical link are shared. Inputs and free-form names are excluded.

Assumptions & checks

Electrical real input power is distinct from mechanical shaft output. AC assumes balanced sinusoidal operation; no cable sizing, motor starting or code approval.
