"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 else can I help you with?
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 are gained or lost it the electrode?
In an electrochemical cell, electrons are gained or lost at the electrodes during oxidation and reduction reactions. At the anode, oxidation occurs, resulting in the loss of electrons, while at the cathode, reduction takes place, leading to the gain of electrons. This transfer of electrons is fundamental to the flow of electric current in the circuit. Thus, the electrodes facilitate the gain or loss of electrons, which drives the overall electrochemical process.
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.
In which direction do electrons flow from the anode to the cathode in an electrical circuit?
Electrons flow from the anode to the cathode in an electrical circuit.
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 the nature of charge on cathod rays?
Cathode rays are negatively charged particles, which are typically electrons. These electrons are emitted from the cathode in a vacuum tube and are attracted to the positively charged anode.
In the production of anode rays why perforated cathode plate is used?
A perforated cathode plate is used in the production of anode rays to allow some electrons to pass through and create a beam of electrons. This helps in generating a focused and directional electron beam for studying the properties of anode rays. The perforations also provide a way for the electrons to accelerate towards the anode, contributing to the formation of anode rays.
What is the difference between a cathode and an anode in terms of their functions in an electrical circuit?
In an electrical circuit, the cathode is the negatively charged electrode where electrons flow out, while the anode is the positively charged electrode where electrons flow in. The cathode emits electrons, while the anode receives them.
What is always true during the operation of a voltaic cell?
During the operation of a voltaic cell, electrons flow from the anode to the cathode through an external circuit, generating an electric current. The anode undergoes oxidation (loses electrons), while the cathode undergoes reduction (gains electrons). This process is driven by a redox reaction occurring within the cell.
In an electrochemical cell where are electrons produced?
Electrons are produced at the anode of the electrochemical cell during the oxidation half-reaction. As the anode oxidizes, it releases electrons that flow through the external circuit to the cathode.
What produces the flow of electrons with a static electric charge?
Anode
What direction do electrons flow in electrolyte cells?
From anode to cathode.
What is the relationship between the cathode and anode in an electrochemical cell?
In an electrochemical cell, the cathode is where reduction occurs, while the anode is where oxidation occurs. The cathode and anode are connected by an external circuit, allowing for the flow of electrons from the anode to the cathode. This flow of electrons generates an electric current in the cell.
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
In a simple cell the cathode or the anode is more reactive?
In a simple cell, the anode is typically more reactive than the cathode. The anode undergoes oxidation, releasing electrons, while the cathode undergoes reduction, accepting those electrons. This difference in reactivity drives the flow of electrons from the anode to the cathode, generating electrical energy.
