Q: A capacitor of capacitance C is charged to a voltage V. If the charge is then removed, what is the potential difference across the capacitor? (2023)
Solution: If the charge is removed, the potential difference across the capacitor becomes 0 volts.
Steps: 6
Step 1: Understand that a capacitor stores electrical energy in the form of charge.
Step 2: Know that the capacitance (C) of a capacitor is a measure of how much charge it can store at a given voltage (V).
Step 3: When the capacitor is charged, it has a certain amount of charge (Q) stored in it, which is related to the voltage by the formula Q = C * V.
Step 4: If the charge is removed from the capacitor, it means there is no longer any stored charge.
Step 5: Since the potential difference (voltage) across a capacitor is directly related to the amount of charge it holds, if there is no charge, the potential difference must be 0 volts.
Step 6: Therefore, after the charge is removed, the potential difference across the capacitor is 0 volts.
