Not as much "rest" and "other" help you to exclude someone as the context. You can say: "...one transformer/several transformers did something and/but the rest of the transformers didn't..." or "...one transformer/several transformers did something and/but the others/ the other transformers didn't...". Both words you have to use with "the" anyway, "the rest" - it's always like that and "the other" means you separate that one or the group.
