Three wires, of the same diameter, are connected in turn between two points maintained at a constant potential difference. Their resistivities and lengths are p and l (wire A), 1.2 p and 1.2l (wire B), 0.9 p and l (wire C). Rank the wires according to the rate at which energy is transferred to thermal energy within them, greatest first.
