How the electric train gets the supply of electricity? What
is the return path of the current?

Answer Posted / baskaran.r

now the supply for traction is 25KV AC.connected through
pantograf. this supply is given to an onload tap changing
transformer with a secondary voltage of 800v. this through
semiconductor devices converted and applied to traction
motor. the return path is the rails through brushes in the axils

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]
