What is the potential energy stored in a capacitor of capacitance C charged to a voltage V? (2021)

What is the potential energy stored in a capacitor of capacitance C charged to a voltage V? (2021)

Step 1: Understand that a capacitor is a device that stores electrical energy.
Step 2: Know that the capacitance (C) is a measure of how much charge a capacitor can store per unit voltage.
Step 3: Recognize that when a capacitor is charged to a voltage (V), it stores energy.
Step 4: The formula to calculate the potential energy (U) stored in a capacitor is U = 1/2 CV^2.
Step 5: In this formula, 'C' is the capacitance and 'V' is the voltage.
Step 6: To find the potential energy, you multiply the capacitance by the square of the voltage, and then divide by 2.
