I'm solving some problems on three-phase systems. I'm doing pretty OK, but there is one problem that I'm not sure about the answer so I have some questions.
We have a three-phase circuit connected in a star connection, which is balanced (since the three impedances have the same value). The neutral wire has an impedance too, that has a value of 5 Ω and 30º. (This value it's different to the other impedances).
They're asking me the value of electric current on the neutral wire. I know it's zero when the system is balanced. However, I'm not sure if the fact of having an impedance on the neutral wire can affect on this.
I know it's a very basic question, but I'm a bit messed and I couldn't find this anywhere, thanks so much for the answers on beforehand!
