Two cables, both with conductor cross-sectional area 6 mm2, are connected in parallel across a common D.C. voltage of 21 Volts.

The resistivity of Cable 1 is ρ = 2.0 x 10-9 Ω.m at 20 °C, while the resistivity of Cable 2 is ρ = 3.0 x 10-9 Ω.m at 20 °C.

Cable 1 is 1348 mm in length.

If 43.2 % of the current passes through cable 1, determine the length of cable 2.

Assume the ambient temperature is 20°C
