Capacitor Calculator

Calculate capacitor size for power factor correction (μF) or capacitor energy (J). Supports kW, kVA input with target power factor.

Motor Current Calculator

Calculate rated current and starting current for AC motors. Supports single-phase and three-phase motors with efficiency and power factor.

Three-Phase Power Calculator

Calculate three-phase active power (kW), apparent power (kVA), and reactive power (kVAR). Also find current from power.
