I should specify when I say physical engineering I just mean chemical, mechanical, electrical, etc. (not software), rather than physics in theory/academia.
I guess engineers are applied physics (in a particular area each), and we need to distribute our deliverables to people who aren’t necessarily experts in every discipline.
It just also makes sense to always define variables.
It’s so funny because I’ve never seen voltage defined as U, and not V haha, proving how if you’re going to have an equation, you’d better define everything, there’s so many reused letters!
U is definitely standard for a difference in electric potential in Europe. Thought to come from “Unterschied”, difference. V refers to electric potential, which as wikipedia says so wisely, should not be confused with a difference in electric potential. Which North American notation does. At least it’s not PEMDAS…

There ya go (only used it up until highschool physics, in Australia, iirc), I definitely have no business reading anything regarding voltage then 😅
