Four wires of the same diameter are connected, in turn, between two points maintained at a constant
\( \mathrm{P} \) potential difference. Their resistivities and lengths

W are; \( \rho \) and \( L \) (wire 1), \( 1.2 \rho \) and \( 1.2 L \) (wire 2), \( 0.9 \rho \) and \( 0.9 L \) (wire 3 ) and \( \rho \) and \( 1.5 L \) (wire 4). Rank the wires according to the rates at which energy is dissipated as heat, greatest first,
(a) \( 4312 \)
(b) \( 4213 \)
(c) \( 1234 \)
(d) \( 3124 \)
