What is the classification of multiple separately derived systems that are connected in parallel?

The classification of multiple separately derived systems connected in parallel is considered "multiple separately derived systems." This term indicates that each system is independently derived from its own source, ensuring that they do not share a common ground or source of potential. When these independently derived systems are connected in parallel, they maintain their distinct separations while being linked together for functionality, such as to provide redundancy or to support increased load capacity.

In contrast, designating them as "two independent systems" does not accurately reflect the nature of their connection, since they are functioning together as a parallel configuration rather than remaining completely independent. Classifying them as "a single separately derived system" disregards the fact that there are multiple sources contributing to the systems' operation. Describing them as a "series circuit" is also incorrect, as series circuits involve components connected end-to-end, which would not apply to independently derived systems operating in parallel. Therefore, the appropriate classification acknowledges their individual nature while recognizing their parallel connection, making "multiple separately derived systems" the correct choice.
