## Main Question or Discussion Point

After we proved Y-Δ transform using superposition theorem, The professor asked us what would happen if you have a Y circuit but a resistor is connected to the middle node. Can you do the transformation?

She answered and said yes, and that resistor will be connected to nothing. How can that be true? Or how do we prove that this is true if it is?
