Moreover, the ampere comes from Andre Marie Ampere, French physicist (1775-1836) who discovered ampere. Moreover, one ampere of current means one coulomb of electrical charge (6.24 x 1018 charge carriers) moving past a specific point in one second. In addition, James Watt was a Scottish instrument maker and inventor whose steam engine contributed substantially to the Industrial Revolution.Īns: An ampere is a unit of measure of the rate of electron flow or current in an electrical conductor. Moreover, the inventor of the Watt steam engine. Who invented the unit watt and when?Īns: Electricity as we measure in units of power called Watts, named to honour James Watt. In this calculation, also the power factor of the resistive impedance load is equal to one. Source: en. Watt’s Law (P = VI)Ĭonverting watts to amps is done using Watt’s Law formula, which states that I = \(\frac\) ![]() The ‘1,000’ factor is there to convert from W to kW we want the resulting power to be in kilowatts. Basically, we just multiply amp by volts. Moreover, the full power of the water running through the pipes is measured by volume × pressure or, to bring it back to the realm of electricity, the power (watts) which the water is producing is calculated by amps × volts. Here’s the simple formula we use to calculate power on a 1-phase AC circuit: P (kW) I (Amps) × V (Volts) 1,000. Also, to understand the key concepts of electricity denoted by watts, volts, and amps, it is helpful to think of electricity as water flowing through a pipe.īesides, amps represent the quantity or volume of water flowing through the pipe, and the voltage represents the amount of water pressure – just like the water pressure that comes out of your shower head or bathtub faucet. Convert Watts to Amps (Detailed Example). We cannot convert from watts to amps or amps to watts directly because the two units measure very different aspects of electrical current.įurthermore, below we will understand the formula to convert watts to amps. In Simple Watts to Amps calculator, any two known values among three (P, I and V) can be used to calculate power in watts, current in amperes or voltage in volts. The formula to convert amps to watts at a fixed voltage is: watts amps x volts. Watts and Amps are different units for measuring or describing electricity. For better experience through mobile phones, use the calculator in landscape position.1.3 Solved Questions for You Watts to Amps Note 1: If you are on mobile phones device, click on the three dots “ …” beside the “Advanced Calculator” to select the simple calculator. In Simple Watts to Amps calculator, any two known values among three (P, I and V) can be used to calculate power in watts, current in amperes or voltage in volts. ![]() You may read more about the difference between Star ( Y )and Delta ( Δ ) Connections. In Advanced Watts to Amps Calculator, We can calculate the electric current in amperes, milliamperes or kiloamperes from electric power in in watts, milliwatts or kilowatts and RMS voltage in volts for DC circuits, AC, 1-Phase and 3-Phase circuits having the Line to Line voltage ( Delta Connection), Line to Neutral voltage ( Star Connection) and Power Factor (P.F). The following two (basic and advanced) calculators can be used to calculate and convert the electric current in amperes from electric power in watts and voltage in volts. How to Convert Watts (W) to Amperes (A) – Simple and Advanced Calculators A watts to amps calculator is a tool used to convert electrical power in watts to electric current in amperes.
