What is a wire of resistance R is melted and stretched to N times?

What is a wire of resistance R is melted and stretched to N times?
Answer : When a wire of resistance \( R \) is melted and stretched to \( N \) times its original length, its resistance changes due to both its increased length and decreased cross-sectional area. ### Step-by-step ... a factor of \( N^2 \) when the wire is stretched \( N \) times its original length....
