The resistivity of a wire

A metallic wire has a definite resistance . IF the wire is stretched in such a way that its length becomes doubled then what will be the resistance of the wire? Consider the volume and the resistivity of the wire remains unchanged.

What is specific resistance and resistivity of a wire? Is it more for thick or thin wire?

What is specific resistance and resistivity of a wire? Is it more for thick or thin wire?

The resistance of a wire of length 80 cm and of uniform area of cross-section 0.025 cm^2 , is found to be 1.50 ohm. Calculate the resistivity of the wire.

The resistance of a wire of length l and diameter d is R . The wire is stretched to double its length. The resistance of the wire will now be

The resistance of a wire is 2 Omega . The wire is stretched to doubel its length. Now the resistance of the wire will become

The resistance of a wire R Omega . The wire is stretched to double its length keeping volume constant. Now, the resistance of the wire will become

The resistance of a wire R Omega . The wire is stretched to double its length keeping volume constant. Now, the resistance of the wire will become
