Joule heating versus resistance – Science Project for kids this Physics project for class 9th and 10th will help the students demonstrate how any conductor gets heated up when an electric current flows through it. The reason behind this phenomenon called Joule Effect is that the conductor offers some resistance. The free electrons of the conductor move to anode from the cathode. During this movement, they collide with the cations and cause the energy of the free electrons to be transferred. The cations now vibrate more vigorously causing heating.
At Projects for Schools, our DIY Science project ideas are focused around demonstrating complicated concepts in a simple and fun manner. In our series of various kits we have also developed a Science fair idea to demonstrate heating effects of current by using simple circuit diagrams.
Since different substances have different resistances,Joule heating versus resistance they produce different amounts of heat even when the same amount of current flows through them. This effect is used in a lot of heating appliances like room heater, water heater, fuses, electric iron and bulbs.
