(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 4 Omega non insulated resistance wire is bent in the middle by 180^@ and both the halves are twisted with each other. What will be its new resistance ?

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 (1 Omega ) is divided into two halves and both halves are connected in parallel. Find the new resistance.

A wire of resistance 2Omega is stretched so that its radius is halved. Determine its new resistance.
