Question

We have two wires a and b of same mass and same material the diameter of the wire is half of that b if the resistance of wire A is 24ohm then the resistance of wire b will be​

Answer 1

Answer:

the wire b will be 1.5ohm

Answer 2

Answer:

1.5 ohm

Explanation:

Same material → same density, specific resistance as they are material property.
