Heating effect of an electric current
WebEffects of electric current When current flows in a circuit it exhibits various effects. The main effects are heating, chemical and magnetic effects. 1. Heating effect When the flow of current is ‘resisted’ generally heat is produced. is is because the electrons while moving in the wire or resistor su er resistance. Web12 de abr. de 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, …

When electrons pass through a wire, they can give some of their energy to the atoms in the wire and make them vibrate faster than their original vibration, so the wire gets hot. We can define this phenomenon as the heating effect of the electric current.
