@ wires of resistence a & b of equal mass and same material are taken the diameter of wira a is half of diameter b if the resistence of wire a is24 ohms find the resistence of wire b

Expert Answer:

For wire A:
rA = Radius and lA = length of the wire
For wire B:
rB = Radius and lB = length of the wire
Given that the two wires are made of the saem material and equal masses. Hence, their density (d) and the specific resistance (ρ) is the same.
