Difference Between Amps and Watts

Amps or Amperes are considered as the unit or SI unit of flowing current or electricity. When Watts is divided by voltage, gives Amps. Measuring the current flow or Ampere is a simple process.

Watts is considered as the unit or SI unit of power. when Amps is multiplied by the mathematical value of voltage, gives Watts. Measuring the Watts is a comparatively complex process than measuring Amps.

What is Amps?

Ampere is often used in its shortened form as "amp" and is denoted as A. Amps or Ampere is the basic unit of measurement of electric current according to the International System of Units or SI.

 He was a physicist and mathematician from France (1775–1836). One Ampere is defined as one coulomb of charge drawn per second.

In a conductor, the rate of flow of electrons is measured in Ampere. 

The value of the electrical charge is 6.24×10^18 electrons in one second. Ampere is one of the 7 basic International systems of Units or SI units.

What is Watts?

Watt is the unit of radiant flux or power. When the amount of current flow into an appliance is one Ampere And the potential difference is one volt, then the rate of work done is one watt.

Watt is also equivalent to 1/746 horsepower. One kilowatt equals one thousand watts. Moreover, most of the electronic appliances used in the house are rated in this unit if measurement, i.e, watts.

Main Differences Between Amps and Watts

  1. Amps are generally denoted as the bold letter A, on the other hand, Watts is generally denoted as the bold letter W.
  2. Amps is named after the scientist André-Marie Ampère. However, Watts is named after an 18th-century inventor from Scotland, James Watt.

Conclusion

The application of amps can only be found in the field of current and electricity. Whereas, Watts is applicable in the calculation of various forms of energy. When an Ammeter is attached to a circuit, it gives the measurement of the flow of current.

Moreover, both Watts and Amps are independent variables, if the value of one changes, then the value of another also changes. If the value of volts remains constant, then watts are directly proportional to Amps.
