Think of a parallel plate capacitor as two big, flat metal plates facing each other with a bit of space between them. Now, connect these plates to a battery. The plate connected to the positive terminal starts losing electrons (because like charges repel), and the plate connected to the negative terminal starts gaining electrons (since opposite

Free electrons in the sheet will travel to the positive plate of the capacitor. The metal sheet is subsequently drawn to the nearest capacitor plate and attached to it, giving it the same potential as that plate. When the gap between the capacitor plates is reduced to d - t, the capacitance increases. Case (2): Thickness is negligible.
