Text Solution

Verified by Experts

When a current flows through a conducting wire, heat is developed and temperature of wire rises. It is known as the heating effect of electric current.
Work done for flow of Q charge `W = VQ = Vlt = I^2Rt`
This work done is converted into heat hence, heat produced `Q = I^2RJ` Coule.s Law of Heating)
Electric Iron, Electric Stove, Toaster, Geyser, Electric room heater, are the appliances based on the heating effect of electric current
