Capacitors: The Storage of Electric Charge
Can you determine which capacitor has more charge? Discharge each of the two charged capacitors through the charge pump, one at a time, to measure how much charge it has. Connect the negative terminal of the capacitor to the positive terminal of the charge pump, and positive to negative. Then the discharge rate is 1 mC/s.
Why does a parallel plate capacitor discharge itself?
When a circuit is made that allows a capacitor to discharge, the electric field in the wire causes electrons to flow from the wire into the positively charged plate (thus reducing it''s net positive charge. At the same time the electric field in the wire causes electrons in the wire to move toward the positive plate of the capacitor.
