At balanced state sum of currents of all phase ie- Ia+Ib+Ic=0 these currents are flowing through neutral so that its value is zero.

Good job jyoti.

In balance condition, the total current equal to zero.

At balance cond. for 3pha sys Ia+Ib+Ic=0,which is the total current following throw the neutral point of 3pha sys.i.e. zero

KCL, in a node sum of all currents is zero. So if we extract another line there is no chance of load drop. So no current flow.

Yes, we apply KCL I(total) = I1 + I2 and I1, I2 are the load current and I (total) is the neutral.

Sum of entering current = sum of leaving current.
I=I1+I2+I3.
I=I1+I2+I3.
