Electrons travel from a heated cathode or filament to the anode. Charge
is a characteristic associated with the electron (much like the color
blue being associated with sky).
Electron speed in a vacuum tube is approximately equal to the speed of light. This speed defines the transit time and thus upper useable frequency of the tube. Nothing travels from anode to cathode. (No protons, no positrons.) Residual gas molecules may be ionized and end up at the cathode or the anode. "Holes" are a convenience tool to explain certain characteristics and operation of solid state devices. Allowing "holes" to be equal a negative thing does not change tube theory. Results are same, same. OK...flame suit on... Dick K9FFK On 12/2/2016 10:52 AM, Mike Waters wrote: Thank you for your comments, Al. But in an amplifier's vacuum tubes (as Jim, myself, and others discussed earlier in this thread), are charges moving from anode to cathode opposite the flow of electrons? 73, Mike www.w0btu.com On Dec 2, 2016 10:19 AM, "Al Kozakiewicz" <akozak@hourglass.com> wrote:Current is the flow of charges, not particles. Charges are carried byparticles such as electrons (negative) or ions (positive), but the particle itself is not the charge. Charges aren't a physical object that has mass or occupies space. Just like gravity - it can be measured and its effects observed and felt, but you can't point to a gravity object.In the case of electrons it is most definitely NOT like a river. ...Actual electrons drift about the conducting medium at rate of something like 1 meter per hour. On the other hand the charge is propagated at near the speed of light. Negative charges flow one way; positive the other.It adds nothing to the understanding and application of electric circuitsto change the convention for current flow.Al AB2ZY_______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps |
