What is a common application of buffering in electrical systems?

In electrical systems, buffering refers to a technique used to stabilize voltage levels within power supplies. This stabilization is crucial because it helps to maintain a consistent voltage output despite variations in load or input voltage. Buffers can absorb sudden changes in the electrical load, which prevents dips or spikes in voltage that could potentially damage sensitive components or disrupt circuit operation.

In the context of power supplies, buffering can involve the use of capacitors or other storage elements that temporarily hold charge. When a sudden demand for power arises, these components can quickly release energy to maintain the voltage. Conversely, if there is an excess, they can absorb it, thereby preventing voltage surges. This process ensures that the supplied voltage remains within safe limits, leading to improved performance and reliability of the electrical system.

The other options pertain to different aspects of electrical safety and efficiency but do not directly relate to the buffering function in maintaining voltage stability.
