Wye or Star Unbalanced neutral

As with a balanced neutral, it is important to use vector algebra to determine what the current in the neutral is. Unlike a balanced circuit, the neutral will not be zero.

The math is over my head, but the information is appreciated.

why did all the currents change to 12amps at time 3:47?

3:47 The image suddenly switched into a balanced one.

Ok, supid question perhaps but if I have for example heating cables as a load, and each cable needs 230V AC . I have decided to use 3-phase 400V circuitbreaker to supply 6 heating cables .Will this formula work keeping in mind that heating cables are purely resistive loads ?

Wow first time ive ever been glad to have taken precalculus

Did you already mention that the instantaneous polarities are out of phase?

Great info thanks for sharing your knowledge. Question : Can you start the calculation on any line, whether A, B or C?

As other have mentioned, your graphic changes toward the end and shows the wrong amperage on the schematic.
Also, you might get in the habit of saying cosine rather than cos. It is confusing enough for newbees. Be nice if you graphed the vectors along with the tabular format. Good video though, it answered my question.

What if we put a cap on neitral will it help?

With the same parameters, where does the 12amps neutral current go if, the neutral conductor is removed.
