A `10 Omega` thick wire is stretched so that its length becomes three times. Assuming that there is no change in its density on stretching, calculate the resistance of the stretched wire.

If a wire is stretched to its length, then

A thick wire is stretched so that its length become two times. Assuming that there is no change in its density, then what is the ratio of change in resistance of wire to the initial resistance of wire

A thick wire is stretched so that its length become two times. Assuming that there is no change in its density, then what is the ratio of change in resistance of wire to in initial resistance of wire

A wire of resistance 1000 Omega is uniformly stretched so that its length increases by 5% . Assuming that the volume of the wire remains the same on stretching, find the resistance of the wire after stretching.

A metallic wire is stretched so that its length increases by 0.2% . Calculate the percentage change in resistance.

The resistance of a wire is R. When this wire is stretched so that its length becomes double, its cross-sectional area becomes half. What will be the resistance of this stretched wire?

A metallic wire of length 1 m is stretched to duble its length. Calculate the ratio of its initial and final resistances assuming that there is no change in its density on stretching.

A wire of uniform cross section has a resistance of 9 Omega. It is cut into three equal pieces. Each piece is stretched uniformly to three times its length and all the three stretched pieces are connected in parallel.Assuming that stretching of wire does not cause any change in density of their material ,calculate the total resistance of the combination described.
