Quest Time CBSE NCERT VI Chapter: Electric currents, Circuits, Cell. For Questions 1 to 10 visit link: Class VI Physics By Jsunil 11. What conductors and insulators? Ans: The materials which allow electric current to pass through them are called conductors. Examples: All metals like Copper,Iron, Silver and Human body. INSULATORS: The materials which do not allow electric current to pass through them are called bad conductors or insulators. Examples: Plastic, Wood, Rubber and Glass. 12. Why do electricians wear rubber gloves and shoes while at work? Ans: It because rubber gloves are an insulator and prevent current to flow in body .Thus saves electricians from electric shock. 13. What do you mean by heating effect of current? Ans: Electric current is actually the flow of electrons in the conducting material. Now, when these electrons flow, they encounter some resistance in the structure of the conductor, which accounts for the "resistance"
