Water Heat
Asked by baidshryans | 21 Feb, 2009, 10:49: PM
Expert Answer

Total heat required for water to reach its boiling point=(2202 /r ) 5

In the later case let the time taken be t.

We have: (2002 /r)t=(2202 /r ) 5

Hence,t=(220/200)2 5=6.05 minutes

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.
