Hi all,
Sometimes ago I did a series of experiments to understand more about current flow and polarities. My finding and conclusion as follows:
Assuming the current convention current flow from + to - in batteries. The same flow assumption is true in capacitor. However, the current flow in an induced voltage conductor(coil) is acting in the opposing direction.
What I mean was that assuming you induce a voltage in a coil and the polarity is showed by the meter. Now if you short circuit the coil, the current will flow from - to +.
A similar line is current flow + to - external of a battery and flow + to -internal of a coil.
I looked through many reference to see what they have about this and so far I could not find a source addressing this. I think it is important as to understand the behaviors of circuits and have correct prediction as well as foundation.
Here is a diagram:
