In this lecture, we will discuss theory and problem solving of Current Electricity for class 12th NEET Physics. This online video lecture is about the heating effects of current prepared by best faculties of Misostudy in English. (https://www.misostudy.com) Heating effects of current: When current flows through a conductor, heat energy is generated in the conductor. The heating effect of an electric current depends on three factors: A.The resistance, R of the conductor. A higher resistance produces more heat. B. The time, t for which current flows. The longer the time the larger the amount of heat produced C. The amount of current, I. the higher the current the larger the amount of heat generated. Hence the heating effect produced by an electric current, I through a conductor of resistance, R for a time, t is given by H = I2Rt. This equation is called Joule’s equation of electrical heating.
