Hello to everybody, I have a doubt about the convention I use to indicate a voltage in a circuit. I use to put an arrow between the nodes in which I want to measure the voltage. The arrow head indicates where I imagine to put the positive cable of my voltmeter. This is how I learned years ago, when I was a student in Italy and France and I have done this way for many years now. I have a colleague of mine who has pointed to me that the IEEE convention states the opposite and the arrow head indicates instead the negative cable of my imaginary voltmeter. I knew that the two conventions exist depending on the geographical area, but I was wandering which particular IEEE standard states this and if this is effectively used for example in north America.
Thanks a lot!
