Question

two wires A and B of equal masses
and the
same metal are taken, the diameter of the
wire A is half the diameter of the wire B
of the resistance of the wire A be 24 ohm
calculate the resistance of wire B​

Answer 1

Answer:

Explanation:

R₁ = 2ρl/A₂

R₂ = ρl/A₂

R₁:R₂ = 2:1

24:R₂ = 2

∴ R₂ = 12Ω
