Like the phones that have a special plug and everything, the cord one still work when the electricity is out and they don’t seem to have batteries in there, so how and why do they still work

*IF* your landline service is from the telephone company and they are still wired for POTS (literally “Plain Old Telephone Service”), their system has its own voltage over the wires, independent of the electric utility.
Increasingly, even so-called “landlines” are VOIP (“Voice Over Internet Protocol”) which runs via your internet router. so if your phone service is from a company like Comcast, or in some areas also AT&T, if the power goes out your router goes out, so your so-called “landline” is also dead.
