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

Options:

  1. Increases
  2. Decreases
  3. Remains the same
  4. Becomes zero

Correct Answer: Remains the same

Solution: 

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

Questions & Step-by-Step Solutions

A capacitor is charged to a voltage V and then disconnected from the battery. If the distance between the plates is increased, what happens to the charge?
Correct Answer: Charge remains constant.
  • Step 1: Understand that a capacitor stores electrical charge.
  • Step 2: Know that when a capacitor is connected to a battery, it gets charged to a certain voltage V.
  • Step 3: When the capacitor is disconnected from the battery, it is isolated and cannot gain or lose charge from the battery.
  • Step 4: Recognize that the charge on the capacitor remains constant after it is disconnected.
  • Step 5: Understand that increasing the distance between the plates of the capacitor affects its capacitance, which is a measure of how much charge it can store per unit voltage.
  • Step 6: Realize that while increasing the distance decreases the capacitance, it does not change the amount of charge already stored on the capacitor.
  • Capacitance and Charge Relationship – When a capacitor is disconnected from a voltage source, the charge stored on the plates remains constant regardless of changes in capacitance.
  • Effect of Plate Separation – Increasing the distance between the plates of a capacitor decreases its capacitance, but since the charge is constant, the voltage across the capacitor will increase.
