  2. The current I in amps is equal to the power P in watts divided by the voltage V. You can use our watts to amps calculator or volts to amps calculator to calculate current in amps, given voltage in volts and power in watts.

  3. Mar 22, 2023 · The Ampere Calculator allows you to calculate the amperage in amperes based on the electrical voltage in volts and the power in watts of an electrical appliance or system. Simply enter the existing voltage in volts and the power in watts, and the Ampere Calculator will then automatically determine the corresponding amperage in amperes.

    In this article we will learn how to calculate amps, prior to that, lets define what it is. Amperes, commonly known as amps, measure the flow of electricity as an electric current. Specifically, they measure the amount of electrons that flow past a certain point per second.

  5. Mar 12, 2024 · The formula to calculate amps is I(A) = P(W) / V(V). Amps are equal to Watts divided by Voltage. You can use an ammeter to measure amps or milliamps. Use Ohm's Law to divide the total voltage by each resistor's resistance in Ohms.

  6. Jul 31, 2023 · To convert watts (electrical power) to amps (electrical current) at a fixed voltage, you can use a variation of Watt's Law formula: Power = Current × Voltage (P = IV). By working backwards, we get the equation: amps = watts ÷ volts, which can be used to convert watts to amps.

  7. This application allows you to accurately calculate the amperage according to Ohm's law (by power, voltage or resistance). The tool understands the difference between direct and alternating current networks (single phase 220V, three phase 380V).
