In SRS, how long do energy capacitors store power for?

In Supplemental Restraint Systems (SRS), energy capacitors are designed to provide power to critical systems such as airbags and other safety features in the event of a collision. The lead time for these capacitors to store energy is significant because it dictates how long they can remain active after the vehicle has been turned off or after an accident has occurred.

The correct answer indicates that energy capacitors store power for about 30 minutes. This duration is critical for ensuring that the safety systems can function properly even after the vehicle was involved in a crash. Within this time frame, responders must be cautious when approaching or working on the vehicle to prevent accidental deployment of the airbags or other SRS components, which could pose a danger to both the rescuers and the occupants.

In contrast, the other choices suggest durations that do not align with the established operational parameters of SRS systems. Capacitors are not designed to hold energy for excessively long periods, as this could lead to a more dangerous scenario if responders do not take the necessary precautions in a timely manner.
