I know how to calculate current in delta connection but just for knowledge purpose I wanted to know from basics why this method(in image) of calculating phase and line current is completely wrong even for balanced load and so for unbalanced load also, so here is a circuit
Of unbalanced load and that is my calculation of phase and line current (which is obviously wrong)
So why this method(method of potential difference) of calculation don't work here, even though in all dc circuits this method works always so why not here?
And what is best approach to solve these types(varying magnetic flux) of complex circuits
