Question: A capacitor is charged to a voltage V and then disconnected from the battery. What happens to the charge on the capacitor?

Options:

Correct Answer: It remains constant

Solution:

Once disconnected from the battery, the charge on the capacitor remains constant as there is no path for charge to flow.

A capacitor is charged to a voltage V and then disconnected from the battery. What happens to the charge on the capacitor?

Step 1: A capacitor is a device that stores electrical energy in the form of an electric charge.
Step 2: When the capacitor is connected to a battery, it gets charged up to a certain voltage V.
Step 3: Once the capacitor is fully charged, it has a certain amount of electric charge stored in it.
Step 4: If you disconnect the capacitor from the battery, it is no longer connected to any power source.
Step 5: Since there is no path for the charge to flow out of the capacitor, the charge remains trapped inside.
Step 6: Therefore, the amount of charge on the capacitor stays the same after it is disconnected from the battery.

Capacitor Charge Behavior – When a capacitor is charged and then disconnected from a power source, the charge stored in the capacitor remains constant because there is no external circuit for the charge to flow.
