I was an electrical engineer before I was a computer programmer and people liked asking questions about Ohm's law and calculating total resistance of resistors in series and parallel.
EDIT: I should clarify... They weren't asking about the theory behind Ohm's law but rather to apply it to various circuits.
Interesting - thanks. I was hoping for more results, but with this falling rapidly off the "newest" page, and with only one upvote, I guess we won't get (m)any more insights.
Edit: Last minute surge and we're on the front page! Amazing - thanks to those who voted - I'm waiting to see if we get any more answers ...
That feels more like asking the difference between a class and object. Its not really asking someone to solve nearly the simplest problem to prove they can can code.
Would the equivalent not be making a basic circuit to do something specific and hence a specific example that has one or two potential obvious issues?
