A unit of electrical energy equal to the work done when a current of one ampere is passed through a resistance of one ohm for one second. [25] The watt-second is the energy equivalent to the power of one watt sustained for one second. For work, in the scientific sense, to be done, a force must be exerted and there must be displacement in the direction of the force. He laid the foundation for the theory of conservation of energy, which later influenced the First Law of Thermodynamics. Advertisements Early Life and Education: Born in Salford, […] Force and Displacement The distance (or displacement) in work is the distance from the start point to the end point.
