Then, the charge that flows through the conductor in t second,įactors influencing the heat developed when a current passes through a conductor.Ĭomplete the following table on the basis of Joule’s Law. If the ammeter shows a current I ampere on applying a potential difference V across the resistor of resistance R Ω Lighting Effect of Electric Current Question 5. It can only be converted from one form to another (Law of Conservation of Energy) As the resistance of Ni-chrome is higher it produced more heat. This based on the concept that energy can neither be created nor destroyed. → In this case which form of energy was converted into heat energy? → How does the ni-chrome wire become red hot while passing electricity through the circuit? Heat Chapter Class 10 Questions and Answers Question 4. Which are the devices that give heating effect of electric current? Heating Effect of Electric Current Class 10 Question 3. Write down the energy changes in them with respect to their use. Some electrical devices are shown in the house of the child.
