State joule law of heating
WebBetween 1840 and 1843, Joule carefully studied the heat produced by an electric current. From this study, he developed Joule's laws of heating, the first of which is commonly referred to as the Joule effect. Joule's first law expresses the relationship between heat generated in a conductor and current flow, resistance, and time. Web"Joule's first law" (Joule heating), a physical law expressing the relationship between the heat generated and the current flowing through a conductor. Joule's second law states …

WebJoule’s law of heating states that, when a current ‘i ' passes through a conductor of resistance ‘r’ for time ‘t’ then the heat developed in the conductor is equal to the product of … WebApr 2, 2024 · E = P t. From (1) E = I 2 R t. Since the power is the power of heating, the energy obtained is the heat energy. So we get the mathematical expression for Joule’s law of heating as. H = I 2 R t . Note. The Joule heating is also known as Ohmic heating, or the resistive heating. This law finds its application in many of the electrical devices used.
