What is the formula for the energy stored in a capacitor?

Step 1: Understand that a capacitor is a device that stores electrical energy.
Step 2: Know that the energy stored in a capacitor depends on two things: its capacitance (C) and the voltage (V) across it.
Step 3: The formula to calculate the energy (U) stored in a capacitor is U = 1/2 C V^2.
Step 4: In this formula, 'C' represents the capacitance in farads, and 'V' represents the voltage in volts.
Step 5: To find the energy, you first square the voltage (V^2), then multiply that by the capacitance (C), and finally multiply the result by 1/2.
