This is named in honour of Italian Physicist Alessandro Volta. 2.4 × 10-1 J. Explanation. A standard fathom is 6 feet long. Its SI units are therefore newtons per square meter, but we make such frequent use of pressure that a derived SI unit, the pascal, is commonly used: (1.4.5) 1 P a = 1 N m - 2 The concept of pressure first developed in connection with studies relating to the atmosphere and vacuum that were carried out in the 17th century. So, Force = rate of . 4. electric potential, the amount of work needed to move a unit charge from a reference point to a specific point against an electric field. The SI unit of energy is Joule. #CarryOnLearning( ^‿^) . SI unit of electric potential difference is volt and denoted by V. This is named in honour of Italian Physicist Alessandro Volta. One kilowatt-hour is defined as the amount of energy consumed by a device in one working hour at a constant rate of one kilowatt.
