Question: If a capacitor is charged to a voltage of 5 V and then disconnected from the battery, what happens to the charge on the capacitor if the voltage is increased to 10 V? (2023)

Options:

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

Correct Answer: Charge increases

Exam Year: 2023

Solution: 

When the voltage is increased to 10 V, the charge on the capacitor increases because charge (Q) is directly proportional to voltage (V) for a given capacitance.

Questions & Step-by-Step Solutions

If a capacitor is charged to a voltage of 5 V and then disconnected from the battery, what happens to the charge on the capacitor if the voltage is increased to 10 V? (2023)
  • Step 1: Understand that a capacitor stores electrical charge.
  • Step 2: Know that the charge (Q) on a capacitor is related to the voltage (V) and capacitance (C) by the formula Q = C * V.
  • Step 3: When the capacitor is charged to 5 V, it holds a certain amount of charge based on that voltage.
  • Step 4: Disconnecting the capacitor from the battery means it cannot gain or lose charge from the battery.
  • Step 5: If the voltage is increased to 10 V, this means we are considering a new scenario where the capacitor is now at a higher voltage.
  • Step 6: Since charge is directly proportional to voltage, increasing the voltage to 10 V will increase the charge on the capacitor.
  • Step 7: Therefore, the charge on the capacitor increases when the voltage is increased to 10 V.
  • Capacitance and Charge Relationship – The relationship between charge (Q), voltage (V), and capacitance (C) is given by the formula Q = C * V, indicating that charge is directly proportional to voltage for a constant capacitance.
