Question:medium
The resistance of a wire is R. It is bent at the middle by 180^∘ and both the ends are twisted together to make a shorter wire. The resistance of the new wire is
The resistance of a wire is R. It is bent at the middle by 180^∘ and both the ends are twisted together to make a shorter wire. The resistance of the new wire is
Show Hint
Halving the length reduces resistance by half, while doubling the area reduces it further by half.
