What are the heating effects of electric current?

Best Answers

Introduction. When current flows through a conductor, heat energy is generated in the conductor. The heating effect of an electric current depends on three factors: The resistance, R of the conductor. A higher resistance produces more heat. The time, t for which current flows. read more

Heating Effect of Electric Current. Generally a battery or cell is used as a source of electrical energy. A potential difference can be developed due to chemical reaction in a cell to set the electrons in motion. so that current will be constituted through a resistor or a group of resistors, which are connected to the battery or cell. read more

The heating effect of current was studied experimentally by Joule in 1941. After doing his experiments Joule came to the conclusion that the heat produced in a conductor is directly proportional to the product of square of current (I2), resistance of the conductor (R) and the time (t) for which current is passed. read more
