|
Answer» should be, respectively, L and A (b) should be, respectively, 2L and A/2 (C) should be, respectively, L/2 and 2A (d) do not matter, since the volume of copper remains the same. R = ρ L /A case a R = ρ L /A case b = R = ρ 2L /(A/2) = 4 ρ L /A case c = R = (ρ L/2) /2A = (1/4) ρ L /A option C has minimum resistance L = L/2 A = 2A 2A = πR² => R = √(2A/π) => Diameter = 2R = 2√(2A/π) ahlukileoi and 25 more users found this answer helpful THANKS 14 4.7 (12 VOTES) Log in to add comment Still have questions?
