What happens to resistance when length is increased 4 times?

What happens to area when the length of wire is doubled?
Answer : When the length of a wire is doubled, the **area** of the wire depends on how the wire is shaped or how it's being manipulated. If we are talking about a **cylindrical wire** (like ... wire doubles but the volume remains constant, the cross-sectional area will become **half** of the original area....

Does resistance increase when length decreases?

Does resistance increase when length decreases?
Answer : No, resistance does not increase when the length of a conductor decreases. In fact, resistance decreases when the length of the conductor is reduced. Here's why: Resistance (\(R\)) is ... and the cross-sectional area stay the same. So, when the length decreases, resistance decreases too....

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....
