Question

does bend in a wire affect its resistance????

Answer 1

Hi friend...... here's your answer........


Yes, and no.
Technically, the resistance of the wire itself doesn't change due to bends in a wire. But the wire is much more than just a resistive component. With enough bends, (turns/loops to be precise) you can make the wire exhibit inductive properties.
Every current carrying conductor produces a magnetic field in the plane perpendicular to the flow of current, and revolving around the conductor.

Hope Helps!!!!

Answer 2

Yes, bend in wire affects its resistance.
If a wire is bent its length decreases and its area increases.
Since resistance α length and resistance α 1/area
Therefore resistance of wire decreases as length decreases and area increases.
