I’m reading a radio theory book, Radio Theory Handbook by Ron Bertrand VK2DQ, which suggests that electron flow (ie current flowing from negative to positive) is used in radio theory and design.
In the electrical trades it is common to hear of current flow from positive to negative. This is called the conventional direction of current flow. This is just what it says, a convention. Current flow is electron flow and it is from negative to positive. Conventional current flow is mostly used in Electrical Engineering. In Radio there is a greater tendency to do what I have done in this book and that is to use electron flow; current flows from negative to positive.
The author then says that one should think of current travelling the opposite way to the arrow in a diode or transistor, which seems like a bad idea to me. I know conventional current flow from positive to negative is technically ‘wrong’, but it’s the convention that is used pretty much everywhere. Is this author right, in saying that electron flow is used in radio theory, rather than conventional current flow?
