Describe what happens to a charged capacitor when it is disconnected

1. When a capacitor is connected to a battery, it gets charged with electrons flowing from the battery to one of its plates, while the other plate gets an equal and opposite charge. Step 2/6 2. Once the capacitor is fully charged, it reaches its maximum potential difference or voltage, and the flow of electrons stops. Step 3/6 3. Now, if we

What happens when a battery is disconnected from a capacitor?

When battery disconnected from capacitor, the charge stored in the capacitor remains the same. The voltage across the capacitor also will remain the same. Q. A capacitor is charged with a battery and then removed from the battery. In this specially designed capacitor, we are able to make the plate size (area) larger without changing anything else.
