Is the positive terminal ALWAYS high potential?

charge here




-------------------

Is the positive terminal always high potential, regardless of if an electron or proton is placed in the "charge here" area somewhere between the two plates, and the negative terminal is always low potential, no matter what?

Mind you, this is high school grade 12 physics.

Positive terminal of WHAT? Is this a battery? A capacitor?

Since the "positive terminal" is DEFINED as being the terminal with the higher potential, I think the answer is yes, but your question is unclear.

And what's this about a proton? What does that have to do with electric potential?
