🔌 Electrical Parameter & Power Calculator

Calculate the missing electrical parameter (V, I, or P) for DC and AC circuits. (Input exactly two parameters)

1. Circuit Type & Known Parameters

Circuit Type

AC Single-Phase (AC 1Φ)

AC Three-Phase (AC 3Φ)

Voltage (V) [Manual Input **OR** Select]

*If calculating V, leave both fields blank.

Current (I) [Leave blank if unknown]

Power (P) [Leave blank if unknown]

Power Factor (PF) [AC only]

2. Hourly Cost Estimation (Optional)

Electricity Price (C_elec) per kWh

USD/kWh

Note on Electrical Formulas: DC Power: P = V ⋅ I (PF=1). AC 1-Phase Power: P = V ⋅ I ⋅ PF. AC 3-Phase Power: P = √3 ⋅ V ⋅ I ⋅ PF. Power Factor is critical for accurate AC calculation.
