(a) State four factors on which the resistance of a conductor depends.
(b) A piece of wire of resistance 20 `Omega` is drawn out so that its length is increased to twice its original length. Calculate the resistance of the wire in the new situation.

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.

A wire of resistance 5Omega is drawn out so that its length is increased by twice its original length. Calculate its new resistance.

A wire of resistance 10 Omega is drawn out so that its length is thrice its original length. Calculate its new resistance (resistivity and density of the material remain uncharged).

A copper wire of resistance R_(0) is strerched till its length is increased to n times of its original length. What will be its new resistance?

If a wire of resistance 25Omega is uniformly stretched until its length becomes three times its original length then its new resistance is

A wire of resistance 12Omega is stretched uniformly till its length becomes three times original length. The change in resistance of wire is

A wire of resistance 10 Omega is drawn out so that its length is thrice its original length. Calculate its new resistance (resistivity and density of the material remain uncharged). " " Or A wire of resistance 10 Omega is drawn out so that its length is increased by twice its original length. Calculate its new resistance.

A 5Omega resistance wire is doubled on it. Calculate the new resistance of the wire.
