which bulb is better - 40W or 60W?
Asked by priya009 | 07 Mar, 2009, 10:30: PM
Expert Answer

Generally,the heat and light both depend on the power of bulb. So the bulb with the 60W ratings generates more heat and light. For domestic purposes usually as the light required is less bulbs with less power are preffered thoug it may vary .

Two wires of copper have the same length but cross-sectional area in the ratio of 3:1. The resistance of the thicker wire is 12 ohm. (a) Calculate the resistance of the thinner wire. (b) Find the equivalent resistance of both these wires, when they are connected (1) in series (ii) parallel (c) If both the wires are connected in parallel to a battery of 24 volt, then find out the ratio of heat produced in the thicker wire to the thinner wire identify the wire if both of them are connected to the same source for the same time duration.
