kw to current calculator
Calculate current from kilowatts (KW), voltage, and power factor for AC or DC systems accurately.
single-phase current calculator
The KW to Current Calculator enables one to calculate kilowatt to amp with the help of voltage and power factor. It covers single-phase, three-phase AC, and DC circuits, assisting in designing appropriate load currents and conductors.
Formula & Table Summary:
Single-phase AC: I = KW × 1000 / (V × PF)
Three-phase AC: I = KW × 1000 / (√3 × V × PF)
DC: I = KW × 1000 / V

A KW to Current Calculator is used to bring electrical power in kilowatts (KW) to the present flow of electricity in amperes (A). It is applicable in AC and DC closed circuits and can represent the power factor in the case of AC. In single phase AC: I=KW /(V x PF) x 1000; V is a voltage; PF power factor. In the case of the three-phase AC: I = KW 1000/ V {sqrt3} / (PF). In circuits that use DC: I = (KW)(1000)/V. Electricians, engineers, students, and students find this tool helpful in assessing load currents, sizing conductors, breaking the protection device, and electrical system planning. Proper conversion to the current based on KW will render the operation of the residential and industrial installation safe and their proper design.
