What does DC working voltage refer to?

DC working voltage specifically refers to the maximum voltage that can be reliably applied across a capacitor's plates without causing any damage. Capacitors have a certain voltage rating which indicates the limit to which they can safely operate; exceeding this voltage can lead to dielectric breakdown or failure of the capacitor. This rating is critical for ensuring the longevity and reliability of the component in its application.

Understanding this concept also helps in selecting the appropriate capacitor for specific electronic circuits. The other options focus on different contexts or applications that do not accurately define DC working voltage in relation to capacitor functionality. This distinction is essential for anyone working with electrical components to ensure safety and effectiveness in their designs.
