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?

Sorry Ohms law is not like a class or an object in any way at all.

he didn't mean literally like a class, it was an analogy. x is to y as z is to ...

Yes but an analogy needs to have some reasonable connection to the thing you are comparing it to for the analogy to make sense.

Engineer roles or Technician?

can you give an example? tia!

  A-->   +--[1 Ω]--+--[1 Ω]--+
         |         |         |
       [1 Ω]     [1 Ω]     [1 Ω]
         |         |         |
         +--[1 Ω]--+--[1 Ω]--+
         |         |         |
       [1 Ω]     [1 Ω]     [1 Ω]
         |         |         |
         +--[1 Ω]--+--[1 Ω]--+    <-- B

Find the resistance between A and B.
