Polyphase circuits

I have a quick question about polyphase circuits. In a Y-Y balanced circuit is the phase current(also line current) the same as the I(eff)? And why is the phase voltage the same as V(eff) as well?

While I was doing the homework I got the answers when setting the phase current and I(eff) equal to each other but I don't know why this is true.
