"from anode to cathode".
Normally, no. Taking a radio valve (electron tube), since the anode is positive compared to the cathode, and since electrons flow from surplus (at the negative cathode) to deficiency (at the positive anode), they do *not* flow from anode to cathode in normal operation.
It's possible to have electrons striking the anode and *knocking off* electrons from it, and then to have those electrons travelling back towards the cathode. This is secondary emission. It was a problem in four-element "tetrode" valves in the early days, but has now been eliminated in practical designs.
Long story short: it's possible, but undesirable and not common.

What happens when smaller area is provided to cathode than anode?
When the area provided to the cathode is smaller than the anode the electrons will still flow.
Where did the electrons from cathode ray come from?
In a cathode ray tube (CRT), the particles, which are electrons, originate at the heated cathode, becoming the so-called cathode rays. The electrons stream off the cathode and rush over to the anode.
What is diode detector?
there are two types:- 1) simple diode detector 2) practical diode detector the diode is common device used in am demodulator. signal(am demodulator signal ) is applied anode and output is taken from cathod
What is a battery end called?
Electrodes... Positive (anode) and Negative (cathode) electrodes which are attached to the terminals. The electrodes provide the chemical energy which is converted to a flow of electrons. And the electrolyte, the electrolyte separates the electrodes but allows for the passages of electrons and ions for the electro-chemical reaction of the electrodes.
What does the resistance of the flow of electrons cause?
it cause no electricity because of the resistance but.... if your question was..... "the caused by the flow of electrons" then the answer well be ( it cause electricity )
What makes currents move?
when there is two potential , due to potential difference ,electron from -ve side(cathode) flow towards +ve side(anode)(this is nature that electrons from cathod attract by anode) , so the electron moves in the path - ---> +, so current flow opp to that flow + ---> -in
Why flow of current from cathode to anode still the flow of electrons is from cathode to anode?
The direction of current, according to convention, is the direction opposite the direction of electron flow. Remember that the anode is where oxidation occurs, so electrons are lost by the anode. These electrons then move from the anode, to the cathode by a wire that usually connects the two compartments. To reiterate, the electrons flow from the anode (site of oxidation) to the cathode (site of reduction). Because electrons flow from anode to cathode, by convention the direction of current is from cathode to anode (the direction opposite the flow of electrons). Hope this helps!
What is always true during the operation of a voltaic cell?
The correct answer is Electrons flow away from the anode and also Oxidation occurs at the anode.
What produces the flow of electrons with a static electric charge?
Anode
What direction do electrons flow in electrolyte cells?
From anode to cathode.
In the production of anode rays why perforated cathode plate is used?
For the formation of the anode ray which is the opposit in direction of the cathod ray.
Cations are attracted to cathod or anode?
DNA is neither cathode or anode, but it is negatively charged, so the DNA molecules will rn from anode to cathode
The relationship between a cathode and an anode involves what?
The relationship between a cathode and an anode involves
What is a cathod and its work?
it is the way of removing the electrons
What happens when smaller area is provided to cathode than anode?
When the area provided to the cathode is smaller than the anode the electrons will still flow.
How are cathod rays produced?
when the cathode filament emits the electron and because of the high vaccum inside the tube with a high voltage who is applied on anode (the destination) the electron will accelerate to the anode and the anode will emits the x-ray photon directly after strike of the mentioned electron. the power of x-ray or peneration is determined of the anode high voltage.
How do you identify capacitor's anode and cathod?
In ceramic capacitors if you observe it then one of its terminal is smaller than other one.Thus,the longest one is its anode and other one is its cathode.
