How to calculate the current carrying capacity of sized
cables, and there is any formula. please send to
'than.achu@yahoo.com'
Answer Posted / raj patel
as you know size/thickness of cable in mm
then Area = 2*pi*(thickness/2)^2
multiple area with density of that material used for conductor like copper, aluminium
so current carrying capacity I = Area*density of material

Can u explain : what is supply for train (whether a,c or d.c ).I know that supply is 25000v a.c .But there is rumour that supply is D.C. And also explain how lights and fans inside the trains are working ,and what type of motors are used in trains whether D.C motors or induction motors .If d.c motor, how it gets supply.If traction motors are used then what are traction motors and its functions and how it differs from other motors and also explain about locomotive . y d.c series motor in train.train wheels r driven by D.C shunt motor ,at what voltage,and at what speed. please reply..............
