What is meant by 'working voltage'?

Working voltage refers to the maximum DC voltage that can be safely applied across a device, such as a capacitor, without risking failure or breakdown. It is crucial for ensuring that electrical components operate correctly and safely under specified conditions.

In the context of capacitors, the working voltage is essential because exceeding this voltage can lead to dielectric breakdown, resulting in component damage or failure, which can affect the overall performance of the circuit. Hence, components are rated with a working voltage to indicate the safe operational limits they can handle.

This understanding is critical for anyone handling electronic components, as selecting components with appropriate voltage ratings helps prevent failures that might result in equipment malfunction or safety hazards.
