CBSE Class 12-science Answered
What will be the resistivity of a wire if it is stretched to double of its original length without loss of mass?

Expert Answer
The resistivity of a wire depends on the nature of material but not on its dimensions. Thus, the increase in length of the wire will not affect its resistivity.
