• the resistance of a wire of the same length and material if the diameter is 1.6 mm of the given measures

Step-by-step explanation:

hope it helps

Answer 2

12.44Ω

Step-by-step explanation:

For a question such as this, the assumption must be that the resistance is inversely proportional to the square of the diameter. The resistance will be ...

20Ω × (1.262/1.6)² ≈ 12.44Ω
