Two cables, both with conductor cross-sectional area 6mm2, are connected in parallel across a common D.C. voltage of 21Volts.
The resistivity of Cable 1 is Ï = 2.0 x 10-9 Ω.m at 20°C, while the resistivity of Cable 2 is Ï = 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
