We know flow of electron is
current . But why electron flow
from negative to positive and
current from positive to
negative?

Answer Posted / g.lakshmi pathi

As a convention we consider the direction of flow of positive charge as direction of current which is opposite to the direction of flow of electrons.current always flow from high potential to low potential.High potential region means region having high concentration of positive charge.

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..............
