It's a voltage source because a battery's function is to maintain a constant potential not a constant stream of charge, which is what a current source provides.

Quick question...
For the oscilloscope,when it shows an ellipse, will the phase angle need to be 90 degrees or it does not matter?

You have an ellipse when two different channels are out of phase, but not necessarily by 90 degrees.
