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

Options:

  1. Charge increases
  2. Charge decreases
  3. Charge remains the same
  4. Charge becomes zero

Correct Answer: Charge remains the same

Solution: 

When a capacitor is disconnected from the battery, the charge remains constant. Increasing the distance decreases capacitance but does not change the charge.

Questions & Step-by-Step Solutions

A capacitor is charged to a voltage V and then disconnected from the battery. What happens to the charge on the capacitor if the distance between the plates is increased?
Correct Answer: Charge remains constant.
  • Step 1: Understand that a capacitor stores electrical charge.
  • Step 2: When a capacitor is connected to a battery, it gets charged to a certain voltage V.
  • Step 3: After charging, if the capacitor is disconnected from the battery, it keeps the charge it has.
  • Step 4: Know that the charge on the capacitor does not change when it is disconnected from the battery.
  • Step 5: Increasing the distance between the plates of the capacitor affects its capacitance.
  • Step 6: Capacitance is a measure of how much charge a capacitor can store per unit voltage.
  • Step 7: When the distance between the plates increases, the capacitance decreases.
  • Step 8: Even though capacitance decreases, the charge on the capacitor remains the same because it is isolated.
  • Capacitance and Charge Relationship – The relationship between capacitance, charge, and voltage in a capacitor, particularly when isolated from a power source.
  • Effect of Plate Separation – Understanding how increasing the distance between capacitor plates affects capacitance and charge.
