Usually to the extent that there are rumors I get too deep. OTOH, there are some who have sought me out and I have taken time after work to explain things. So much depends on where the person is going in their career. I believe everyone should be able to understand what happens when a resistance is introduced in series with a load in a parallel circuit and also when that series load is on the neutral of a multiwire circuit up to an including the incoming service conductors. Beyond that it is kind of depending on what they do. I do some work with fire alarm, process controls etc. I am also self taught. I often have to go back and refresh on DC motors, induction theory, etc. but I always remember it exists.

I know what I don't know, and I know where to go to find it!
