in single phase we get 220 volt and in three phase 4420 v
why this
second Ques= in case three phase star conection our
neutrul becom disconect what happan
3 Q=== a three phase house load and have unbalce load on
different pahse diffrent current eg phase a 7A b 8A c
5A and voltage is 440 than how calculate it total load in
kw pl give formula thanks

1) the voltage Line to Line is the sum of two phases and these phases have different angles so when we add them respecting to the angle we get vector which is located between the two so, it's drawing is a triangle.
2) If your loads are three phase will not use the neutral and if they are single phase 120 volts they will not work because it is open circui.
3) I am not sure, but I think you can calculate phase power alone then add them together. I think in this case your machine will be damaged because it is unbalanced.
