Let's go through some examples to help nail the conversion process. Amp chart Desired data Kilovolt-Amps (kVA) Single-phase Volts x. 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. In Northern America and Western Japan, this usually happens 60 times per second, or 60Hz / hertz. A flashlight with a battery uses a direct current.ĪC stands for alternating current, when the current periodically changes direction. 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. In the hose analogy, the volts would be the water pressure. They measure the force required to make the electrical current (amps) flow. In this formula, the amount of power (in kW) is equal to the power factor of the load (PF) multiplied by the phase current measured in Amps (A), times the RMS voltage (V), and divided by 1000.

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). 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 are amps?Īmps are amperes, a unit which measures electrical current. To help understand the conversion of watts to amps, let's go through what each of these units represent.
