This Do It Yourself science project kit help students to understand heating effect of electrical current and concept of variable resistance in circuit. Heating effect of electricity is one of the widely used effects in the world. When electric current is passed through a conductor, it generates heat due to the resistance it offers to the current flow. Kit will help to understand working of different electrical appliances like electrical heater, iron, hot plate, etc. Kit helps in better understanding of Joule's Law Of Heating. It demonstrate relation between of wire and resistance in circuit. It help to understand working of variable resistance in circuit.
