WebStep 1. Statement of Joule's law Joule’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 the square of the current, the resistance and time. Step 2. Mathematical explanation WebApr 12, 2024 · Heating is associated with loss in electric circuits. Imagine current passing through a resistor and the body of the resistor heating up. The heat generated is the loss of energy and is usually called heating loss or I2Rt loss. With Joule's law of electric heating equation, we can determine the Joule equivalent of electrical energy. However, we ...
WebApr 6, 2024 · Application of Heating Effect of Electric Current At the point when an electric flow moves through a conveyor, it creates heat due to the conductor's impedance to the flowing current. Heat is generated in the conductor as a result of the work done to overcome the impediment to the current. WebMar 27, 2024 · (i) Heating effect of electric current : When an electric current is passed through a high resistance wire like nichrome, the resistance wire becomes very hot and produces heat. This is called heating effect of electric current. (ii) P = V ×Q/T P = VI E = P × t = VI × t = VIt E = IRIt [V = IR; Ohm's law] = I 2 Rt.
WebJul 1, 2024 · The heating effect of current is defined by Joules law of heating. It is also called ohmic heating and resistive heating. In a conductor when an electric field is applied across its ends, the free electrons available in it start … WebH=I 2Rt. H=1 2×12×60. H=720J. (c) The heat produced by the heater will become one - fourth because heat produced is directly proportional to the square of the current. (d) …
