I saw this section somewhere in the forum: Picture 2 plates charged to a voltage V, w/ capacitance C. Of course Q = C*V. An electron is placed in between the plates & released, & it moves towards the positive plate. Said electron with its negative charge now adds to the positive charge already on the plate resulting in a decrease in the cap voltage. Can you help me understand the bold part? What does "positive charge" mean here? I think it should be "positive ion".
