A conducting wire has a resistance R. It is stretched to double its initial length. Calculate its newresistance in terms of R
Question
Solution 1
The resistance (R) of a wire is given by the formula R = ρL/A, where ρ is the resistivity, L is the length, and A is the cross-sectional area.
When the wire is stretched to double its initial length, its volume remains constant. The volume of the wire can be given as V = AL, so when the length is Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
