You need to show your work. We can't say much about what you did wrong if we don't know what you did.le@rner said:
A capacitor is an electronic component that stores electrical energy in the form of an electric charge. It is made up of two conductive plates separated by a dielectric material.
A capacitor stores energy by accumulating an electric charge on its plates. When a voltage is applied to the capacitor, the positive plate accumulates a positive charge while the negative plate accumulates a negative charge. This creates an electric field between the plates, which stores the energy.
The unit of measurement for energy stored in a capacitor is the joule (J). This is the same unit used to measure energy in other forms, such as heat or mechanical energy.
The energy stored in a capacitor can be calculated using the formula E=1/2CV^2, where E is the energy in joules, C is the capacitance in farads, and V is the voltage across the capacitor in volts.
The energy stored in a capacitor can be released by connecting the two plates with a conductive material, such as a wire. This allows the stored charge to flow from one plate to the other, releasing the energy in the form of an electrical current.
