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.
