Three cylindrical wires are made of the same material. Their lengths and radii are wire 1: length ℓ, radius 2r wire 2: length 2ℓ, radius r wire 3: length 3ℓ/2, radius r/2 A potential difference V is applied across the length of the wires. Rank them according to the current that flows through them, greatest first.
