unfortunate and miserable
The best response is the first reply because downtrodden means trampled upon, crushed, depressed. One way you can help yourself in the future when looking to determine the meaning of a word is to try to replace it with synonyms. That said, if you replace “downtrodden” with “depressed” or “sad,” the sentence still makes perfect sense. However, what if you don’t know synonyms? In that case, try to look at the parts of the word. For instance, the prefix of “downtrodden” is “down.” That said, “down” is typically a word associated with “sad.” Thus, one could make the connection that “downtrodden” is synonymous with “unfortunate” and/or “miserable.”
The difference between the split ring commutator in a DC motor and the slips rings in an AC generator can be tricky. The split ring makes changes in the rotation every so often. A slip ring just stays in place and is only used as a connector. So a slip ring is for DC, whereas the split ring is used for AC.
That statement may just be true
This kind of seems like a personal question...
