Which circuit element is responsible for storing electric energy?

• A. Transistor
• B. Capacitor
• C. Inductor
• D. Diode

Answer: (B)

The circuit element responsible for storing electric energy is the capacitor. A capacitor works by accumulating charge on its plates when a voltage is applied across it. This charge storage creates an electric field between the plates, which allows the capacitor to hold energy in the form of an electric field. The energy stored in a capacitor can be released when the circuit requires it, making capacitors essential in various applications like smoothing out voltage fluctuations in power supplies or providing bursts of energy in timing circuits. While inductors also store energy, they do so in the form of a magnetic field, which is different from how capacitors store energy. Inductors are primarily used in applications involving alternating current and can behave quite differently from capacitors under certain conditions. Therefore, while both capacitors and inductors store energy, the question specifically pertains to the element that stores energy in the same way that capacitors do, which reinforces the validity of the capacitor as the correct answer.
