Joule's law is a physical law expressing the relationship between the heat (q) generated by a current (i) flowing through a conductor of electrical resistance (r) . Joule heating (also: resistive or ohmic heating) is the process where electric energy is converted into heat as the current flows through a. When an electric current is passed through a conductor, heat is produced after some time which is called the heating effect of current this effect is also called as . A quantitative form of joule's law is that the heat evolved per second, or the electric power loss, p, equals the current i squared times the resistance r, or p = i 2r. This is joule's law and j is called mechanical equivalent of heat (1) from w = jq if q = 1 then j = w hence the amount of work done necessary to produce unit.
