thingmaker3,
A truthful acknowledgment is all that is required."Current flow" is indeed a redundant term. I'm not fond of the phrase "ATM machine" as it is also redundant. But you don't see me insisting the banks all change their ways.
He believes that there is confusion about what charge and current mean. Especially for beginners.None of the "meat" (what little of it there is) in Beaty's material on charge is anything new. He embellishes this with smoke and mirrors - simply holding up common semantic practice as a straw-man argument while launching ad-hominem attacks at an undefined "them" and "they."
As long as he does not get personal.simply holding up common semantic practice as a straw-man argument while launching ad-hominem attacks at an undefined "them" and "they."
Perhaps, but it does not make what he is saying false.Beaty is in love with the embellishment of the argument.
Which argument are we talking about now?The argument itself is contained in most textbooks.
He and I have no problem with that.I've no clue why Beaty (and others) are unable to go from "current is a flow of charge carriers" and "current density is proportional to conductivity and electric field" to
Because the true mechanism for controlling the collector current is Vbe. As the equation in Sedra and Smith shows. The beta can vary all over the map, as it does at different frequencies and Q points, but as long as you keep Vbe steady, the emitter current will not change. That makes a BJT a voltage controlled device. Ratch"base current times Hfe equals collector current." Maybe they didn't read the text books as well as they thought they did."base current times Hfe equals collector current." Maybe they didn't read the text books as well as they thought they did.
