Hi
I'm trying to understand electrical safety from http://www.allaboutcircuits.com/vol_1/chpt_3/1.html. In conventional flow notation the electrons moves from + to -?

In electron flow notation electrons moves from - to +?

Is the next circuit a conventional flow notation or electron flow notation?If it is an electron flow notation I'm lost

 

It is an electron flow.

electrons have NEGATIVE electric charge potential.

Doesn't matter what the voltages are when measured. The one which is negative in respect to the other will be the SOURCE of physical electron flow.

Most math involved in bias and amplification electronics doesn't care WHAT is flowing, so anyway that is comfortable for your understanding is proper.

The math works both ways for 99% of the situations, it's the human element and trying to understand the glaring opposites of reality vs. convention that causes problems.

Rest assured that whatever you decide is appropriate will not matter as it relates to your future use and enjoyment of electronics.

 

conventional or actual flow of electron, in either case shock is felt if it flows through.

 

Thanks for your help
