Horsepower (Electric)
Electric horsepower (hp) is a unit of power used to measure the rate at which electrical energy is converted into mechanical energy or work, equivalent to approximately 746 watts.
History/Origin
The electric horsepower was developed as an adaptation of the mechanical horsepower to quantify electrical power output, especially in electric motors and generators. It became a standard unit in electrical engineering to express the power of electric motors and appliances.
Current Use
Electric horsepower is used primarily in specifying the power of electric motors, generators, and other electrical devices, particularly in industries where electrical power measurement is essential for performance and efficiency assessments.
Attowatt
An attowatt (aW) is a unit of power equal to 10^-18 watts, representing an extremely small amount of power.
History/Origin
The attowatt is part of the SI prefix system introduced to denote very small quantities, with 'atto-' representing 10^-18. It has been used mainly in scientific contexts to measure minuscule power levels.
Current Use
The attowatt is rarely used in practical applications but may be referenced in scientific research involving extremely low power measurements, such as in quantum physics or nanotechnology.
