WebJoule's Law of heating. According to Joule's Law of heating, heat generated in a conductor is given by: H=VIt= RV 2t=I 2Rt. 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.
