Electrical theory

But your comment was false and misleading to anyone in the electrical trade. There is advanced theory like semi-conductors and practicle theory like conductors and insulation and the stuff for non-electrical people like electricity is like water.

I stand with: installers and designers need to know the basic practicle theory while troubleshooters need more advanced theory and practicle experience.

I disagree it was false.
Again, it wasnt for you.
But you insist...
Im a 30+ electrician and a very good teacher. I assume you doubt that?

Current does flow on all possible paths and this is covered in the basics involving Ohm's and Kirchhoff's laws.

More resistance a particular path has the less current it will carry but current doesn't seek out only the lowest resistance path which is possible misinterpretation when people say current takes path of least resistance. Stating the most current will flow on path of least resistance is more accurate.

Yes, i know sir.. thx

That is true only if you are discussing the amount of current on each path. The basic concept is the path not the amount.

It's meaningless without discussing the amounts. Without specifying a minimum amount you can't even define what is a path.

My advice to the OP stands; understand Ohm's law.

In post #1 the the statement was made "electricity takes all paths, more current will take the least path of resistance". Then the question was asked "what helped you have a better grasp what will happen in a circuit based on theory or in general".

My advice, to an installer was to learn the basics of electricity and put them into practice. While a troubelshooter should learn some advanced topics.
 
What is a "switchgear technician"? And what do they do?

Op, BOOKS are a solid and proven way to learn. NOT youtube! Someone willing to open a book and pick up a pencil. Too many today think they will get an education in forums. A deeper understanding affords much more competent troubleshooting.

Here is a question as we used to inspect switchgear on a PM, why would we shoot switchgear with a FLIR camera? What would that tell us? How do we fix it and why? Hint, it drives back to the very basic Ohms laws.

We provide and control the path... it doesnt take all paths.

Not trying to take sides or get in a pissing match, but just for constructive criticism, I really didn't think that was a very good comment. I'm not really even sure what you were trying to say. I think you were trying to say something like "we control the path so that it doesn't take the paths we don't want it to take"? Maybe?
