Firstly, I would wish to thank our Social Science teacher.. who gave her immense support, dedicated his/her time towards it and made us understand how to make this project. Without his/her guidance, the project would not have been complete. The matter contained in it has been widely taken from the internet. The source of the newspaper article is The Times of India. The statistical data has been extracted from

Why is a series arrangement not used for connecting domestic electrical appliances in a circuit? 2. A piece of wire of resistance 20 Ω is drawn out so that its length is increased to twice its original length. Calculate the resistance of the wire in the new situation. 3. In the given circuit, resistors A and B are made up of same metal and are of the same length but, A is thicker than B. 4. Which of the two ammeters will show a higher reading? Justify your answer. 5. The resistance of a metal wire of length 1 m is 10 4 Ω at 20 C. If the diameter of the wire is 0.15 mm, find the resistivity of the metal at that temperature. 6. Study the following circuit and find the potential difference across 4 Ω resistor. 7. The parallel combination of two 10 Ω resistors are placed across the terminals of a 24 V battery. (a) What is the effective resistance of the parallel circuit? (b) What is the current through the entire circuit? (c) What is the current through each branch of the circuit?

6 8. Find the equivalent resistance across the two ends A and B of the following circuits. 9. Electrical resistivities of some substances, in ohm-metre, at 20 C are given as follows: Silver Copper Tungsten Mercury Iron Nichrome (a) Out of the two silver and copper, which one is a better conductor of electric current and why? (b) Which substance is preferred to be used for electrical transmission lines? Give reason. (c) Name the material that you would advice to use in the heater element of electric heating device and why? 10. Consider the circuit shown in the diagram. Find the current in 3 Ω resistor. 11. An electric geyser rated 1500 W, 250 V is connected to a 250 V line mains. Calculate : (i) the electric current drawn by it. (ii) energy consumed by it in 50 hours. (iii) cost of energy consumed if each unit costs Two lamps, one rated 60 W at 220 V and the other 40 W at 220 V, are connected in parallel to the electric supply at 220 V. (a) Draw a circuit diagram to show the connections. (b) Calculate the current drawn from the electric supply. (c) Calculate the total energy consumed by the two lamps together when they operate for one hour.
