Nettet26. mar. 2024 · Joule heating Ionic conductors Electrolytes Zero-phase frequency Electrochemical corrosion Introduction When an electric current passes through an electrical conductor, it generates heat by converting electrical energy into thermal energy. The conversion was discovered to follow Joule’s law in 1841. NettetJoules law can be stated as the quantity of heat generated (H) in a conductor of Resistance (R), when a current (I) flows through it for a time (t) is directly proportional to the square of the current, the resistance of the conductor, and the time for which the current flows. So, H=I 2Rt. Now, for a conductor following Ohm's Law, V=IR, or, I ...
