What happens when positive current hits a capacitor plate?

When positive current flows to a capacitor plate, it leads to the accumulation of positive charge on that plate. Capacitors consist of two conductive plates separated by an insulator. When a voltage is applied, electrons are drawn away from one plate and pushed toward the other. If positive current is applied to one of the plates, it causes electrons to leave that plate, resulting in an excess of positive charge.

This stored charge is what allows capacitors to hold and release energy. The electric field established between the two plates due to this charge difference is essential for the capacitor's function in circuits, allowing it to influence voltage and current in a controlled manner. Thus, the scenario where positive current hits a capacitor plate indeed leads to a buildup of positive charge on that plate.
