On what factors does resistivity of a coductor depend ? (iii) Why alloys like constantan and manganin are used for making standard restores ?

What is the resistance of a conductor ? State the factors on which resistance of a conductor depends? How is it related to conductivity of the conductor?

What are the factors on which resistance of a conductor depends? Why are coils of electric toasters and electric irons made of an alloy rather than that of a pure metal?

Define resistance of a conductor. What is its cause? Explain the factors on which the resistance of a conductor depends.

(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.
