Hi, can you explain me for example line one 25 A & line two 65 & line three 40 how calculate what's amp neutral.

Rstar said:   9 years ago
It is balanced load so the neutral current is zero. We want proof to let do one thing remove the neutral core and observe the circuit there no different.

The current flows through neutral when the load is unbalanced. In balanced state, Ia + Ib + Ic=0.

Thanks for all your explanation of the answer.

What is the neutral current?

Sangram das said:   8 years ago
Here, Ia + Ib + Ic = 0.

Siddu said:   8 years ago
The sum of all the phase=0 so that's why neutral=0.

Zero is the answer. Since Ia+ Ib +Ic=In=0.

Here Ia + Ib + Ic = 0is called neutral.
