WebFeb 16, 2024 · This effect of electric current is called heating effect of electric current. The heating effect of electric current depends on three factors: 1) The resistance, R of the conductor. A higher resistance produces more heat 2) The time, t for which current flows. The longer the time the larger the amount of heat produced 3)The amount of current, I ... Joule’s law of heating describes the factors on which the heat generated in a conductor depends when an electric current is passed through it. Let us assume that a current \(\left( I \right)\) flows through a resistor of resistance \(\left( R \right)\) for time \(\left( t \right).\) Let \(\left( Q \right)\) be the electric … See more All devices do not generate heat on passing electricity through them. Devices that use high resistance wire as a heating element can only … See more 1. Calculate the heat given out by a filament of the bulb in \({\rm{20\;s,}}\) when its resistance is \(4\;{\bf{\Omega }}\) and the potential difference across its ends is \({\rm{12\;V}}{\rm{.}}\) Sol: Given, the time for which the bulb … See more 1. Why is heat produced in a conductor on passing an electric current through it? Ans:When a potential difference is applied across the ends of … See more From this article, we can conclude that when electricity is passed through a conductor, it becomes hot because of the heating effect of the electric current. The heat produced in a … See more WebJoule’s law is a mathematical description of the rate at which resistance in a circuit converts electric energy into heat energy. The English physicist James Prescott discovered that the amount of heat per second that … i am extra thankful for you
