Answer / amarnath
As per standards for Aluminium cable 1sq.mm can carry 1A.
and in case of Copper cable 1 sq.mm can carry 4A.
If theres any formula to calculate please do let me know as
well....

Answer / anilkumar
As per standred there is no formula, its only depend on
cable manufacture cataloge and we following same as what
amarnath said AL cable current carrying 1A per SQMM and
copper cable carring 4A per SQMM.

Answer / murugadoss.a
Dear all please consider the length of the cable and voltage droup. Depends on the size the resistance value should be varies. For 3 phase 3.2% valtage droup allowed and 1 phase system 2.5% valtage droup alowed. before going to select the cable size to consider these all.

what is the ohmic value of transformers
ii) A shunt motor supplied at 230V, runs at 900 rpm when the current is 30A. The resistance of the armature is 0.4 ohms. Calculate the resistance required in series with the armature to reduce the speed to 600 rpm, assuming that the armature current is then 20A. [12]
