Consider a wire of length l, area of cross section A, and resistivity `rho` with resistance `10 Omega`. Its length is increased by applying a force, and it becomes four times of its original value. Find the changed resistance of the wire.

Consider a wire of length l , area of cross-section A and resistivity rho and resistance (1)/(5) Omega . Its length is increased by applying a force on I and its length increases by four times of its original length. Find the new resistance in ohms of the wire.

A wire of resistance 4 Omega is stretched to four times of its original length resistance of wire now becomes

If the area of cross-section of a resistance wire is halved, then its resistance becomes:

A wire of resistance 10Omega is stretech to thrice its original length. The resistance of the wire will be

The resistance of a 10m long wire is 10 Omega . Its length is increased by 25% by stretching. The resistance of the wire is now

A piece of wire of resistance 20 Omega is drawn so that its length is increased to twice is original length. Calculate resistance of the wire in the new situation.
