![]() ![]() Let's go through some examples to help nail the conversion process. Advertisements Watts to amps conversion examples Power supplied to homes and businesses uses AC supply. In Europe, the UK, East Japan and most of Australia, South America, Africa andĪsia, the current changes direction 50 times per second, which is 50Hz. The power P in watts (W) is equal to the power factor PF times the phase current I in amps (A), times the RMS voltage V in volts (V). AC single phase amps to watts calculation. For alternating currents, the 2.5 kW amp transformation is different for a single phase and a 3 phase system the power factor is needed in both cases. The power P in watts (W) is equal to the current I in amps (A), times the voltage V in volts (V). In Northern America and Western Japan, this usually happens 60 times per second, or 60Hz / hertz. For the conversion of 2.5 kW to amp check whether your electric current is of type direct or alternating flow of electric charge, as explained in details on our article Watts to Amps. A flashlight with a battery uses a direct current.ĪC stands for alternating current, when the current periodically changes direction. For example, find the current of a circuit with 1 kW of power at 120 volts. ![]() North American homes typically use 120V for their electrical supply, whilst 230V is common acrossĭC stands for direct current, when the current flows in one single direction. Thus, for DC and single-phase AC circuits, the formula to convert kilowatts to amps is: 1 I(A) P (kW) × 1,000 V (V) The current I in amps is equal to the power P in kilowatts divided by the voltage V in volts. In the hose analogy, the volts would be the water pressure. They measure the force required to make the electrical current (amps) flow. It uses increased water volume and higher water pressure the same applies to the wattage if amps and volts are increased. A water wheel would turn faster and longer, generating more energy if Multiplying amps (water volume) by volts (water pressure) gives you the wattage (the resulting power or energy). The formula to convert amps to kilowatts for three-phase AC circuits where the current, line to line RMS voltage, and power factor is known is: P (kW) I (A) × V L-L(V) × PF × 3 / 1,000 Thus, the power P in kilowatts is equal to the current I in amps multiplied by the voltage V in volts multiplied by the power factor PF multiplied by the. Watts represent the amount of energy produced by the amps and volts working together. In this analogy, the quantity (volume) of water would be the amps. It can be helpful to imagine electrical current as water in a hose. What size genset is needed to start a 3 phase electric motor Direct on Line (DOL) start HP of. What are amps?Īmps are amperes, a unit which measures electrical current. Thus, the power P in kilowatts is equal to the current I in amps multiplied by the voltage V in volts, divided by 1,000. To help understand the conversion of watts to amps, let's go through what each of these units represent. To convert amps to kilowatts the power formula can be used, which states that I P ÷ E, given that P is the power in watts, I is current in amps, and E is voltage in volts.
