Watt Watt The watt (symbol: W) is a unit of power. In the International System of Units (SI) it is defined as a derived unit of 1 joule per second, and is used to quantify the rate of energy transfer. When an object's velocity is held constant at one meter per second against a constant opposing force of one newton, the rate at which work is done is 1 watt. In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt
Coefficients of potential two conductors carry equal and opposite charges, formula_20 Coefficients of potential In electrostatics, the coefficients of potential determine the relationship between the charge and electrostatic potential (electrical potential), which is purely geometric: where "Q" is the surface charge on conductor "i". The coefficients of potential are the coefficients "p". φ should be correctly read as the potential on the i-th conductor, and hence "formula_2" is the p due to charge 1 on conductor 2. or more formally Note that: The physical content of the symmetry is as follows: In general, the coefficients is used when describing system of conductors, such
