> (btw have never heard voltage be called tension, TIL)

It's the main word for voltage in french and I checked wiki before posting. It was listed as an alternative to voltage so I kept it, but I should have realized it wasn't common

Hopefully helpful comment: "tension" is sometimes used as an alternative to "voltage" in English, but it's typically only in the case of power delivery. e.g, "high-tension 50kV power lines." I don't think I've ever seen it applied to common control panel voltages like 5V or 24V.
