The answers of the following stated questions are covered in this video :-
Question#1: Can current flow through a circuit without potential difference? Explain.
Question#2: If aluminum and copper wires of the same length have the same resistance, which has the larger diameter? Why?
Question#3: What is resistance across open switch and close switch of a circuit?
Question#4: A bird is sitting on a high voltage transmission line, but it is not electrocuted. Why? When it tries to fly, it touches another bird that is sitting on second transmission line of the pole. Now, it is heavily electrocuted. Why?
Question#5: You are given five resistances of different magnitudes. But you are asked to form a circuit whose resistance is smaller than any given resistance. How can you make such circuit with given resistances?
Question#6: You are given n wires, each of resistance R. What is the ratio of maximum to minimum resistance obtainable from these wires?
Question#7: Two electric bulbs marked 100W, 220V and 200W, 220V have tungsten filaments of the same length. Which bulb will have thicker filament?
Question#8: Why are we advised not to touch electric switches with wet hand, first dry your hands?
Question#9: Why is it dangerous to touch a live wire while standing on earth bare footed?
Question#10: Sometimes, if your one of the car’s head lamp is burnt or not working but second lamp still gives light. What do you conclude about connection of head lamps from this observation?
Question#11: Show that volt ampere is equal to watt (SI unit of power).
