Round so they will not fit and fall through the hole. A square would fall through if rotated to the corner to corner direction of the opening.

How far apart are they ? Lol

I don’t need any internet or calculator to realize there is not enough information.

For electrical engineers, my father told me this is one they would ask sometimes when he was working:
What is Ohm’s law?

Close
I = V/R

psyche, you got it.

My father actually said some new EE grads would not know it at the job interview. This was around late 80’s. I graduated EE in 93 and could not imagine one of my fellow grads not knowing it. It is like the main building block of electrical.

In my father’s group they were interviewing people for high voltage power transmission at a major power company. Basic electrical concepts are used all the time in power. My father also would tell me about how in the 80’s they had become more selective in hiring because of Human Resources mandates and were forced to interview from only the highest gpa graduates. The problem with that is they would end up with book smart engineers that lacked common sense and the ability to factor in real world issues such as equipment cost vs. benefit and future load demand vs power generation/supply capabilities, etc.

Before the mid to late 1980s, newly graduating electrical engineers could typically be very selective in their job search but it became much harder to find jobs after the late 80’s economic changes.
