Why anode rays also known as canal rays?
Anode rays are also known as canal rays because they were discovered to be positively charged particles produced in a cathode tube when the cathode rays strike a gas at low pressure. The particles travel in the opposite direction of cathode rays and move towards the anode or positive electrode, hence the name "anode rays."
What is the cathode in an electrochemical cell?
The electrode at which a reduction reaction occurs.PhysicsA cathode is the element of an electron tube from which electrons flow. Back in the day, current was thought to be positive, but we understand things differently now. In the "old school" version, the cathode was the element into which positive charges flowed. But that's usually not what is taught for the simple reason that it's a classical physics approach and isn't at all as useful as the idea that the cathode is the element from which electrons leave to go to the plate.In a two-element tube, the cathode has a compliment called the anode, or plate. Electrons flow from the cathode to the anode. Not the other way. There are tubes with three, four, and more elements, but they have these two basic elements.ChemistryThe cathode is the electrode of a polarized electrical device, such as a galvanic cell, out of which positive electric current flows. In a battery like the one in a vehicle, the positive terminal is the cathode. The car battery, which is a lead-acid battery, also has an electrode that is the compliment to the cathode: the anode. It's the negative terminal of the battery, and positive electric current flows into this electrode.The Wikipedia article on the cathode covers both the chemistry application of the term as well as the physics application, and a link is provided.
What are cathode rays made from?
Cathode rays are a stream of electrons originating from cathode and moving to an anode, when high voltage electric potential is applied to the electrodes sealed in a glass tube containing gas at low pressure.Cathode rays are stream of negativley charged electrons getting detached right from neutral molecues due to high voltage and driven right from cathode to anode.
Are cathode rays deflected toward a negatively charged plate in an electric field?
Yes, cathode rays are deflected towards a positively charged plate in an electric field. The negatively charged particles in the cathode rays are attracted to the positive plate, causing the deflection.
What minerals are in a car battery anode?
Common minerals found in a car battery anode include lead dioxide and lead sulfate. Lead dioxide is typically used in the positive plate of the anode, while lead sulfate forms on the negative plate during the discharge process.
What is meaning of perforated cathode?
The. Cathode plate consists of small holes known as perforated cathode plate
What is a synonym for electrode?
According to Thesaurus.com synonyms: copper cathode, inert anode, inert cathode,plate, wire, zinc anode

How are cathode rays originated?
its negatively charged particles of matter,Thomson knew that opposites attract but these the positive charged anode,so he reasoned that the paticles must be negatively charged! : )! Wooooo! Go J.J Thomson
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.
Do the rays produced in cathode tube deflect towards negative plate?
The electron beam produced in the cathode is essentially negative (with respect to the anode), therefore it tends to go towards potentials above the cathode's potential (more positive or less negative, as you wish).
What would the cathode be in a nickel and copper electrolyte cell?
Ni(s)
What invention in the 1940 was first used in a car using 2 pieces of metal and is rechageable and is now smaller?
the invention was a tri-ode diode which is an electronic gas filled tube with an anode and a cathode and one more switching element. The anode is actually the negative plate and the cathode is the positive side. The third element is a switch for on and off.
Parts of x-ray tube?
it contains mainly 1.cathode 2.anode 3.anode 4.filament 5.filter 6.belligerence window copper 8.tungsten filament 9.lead plate vaccum, x-ray
What is the operations of a triode valve?
A triode valve amplifies electrical signals by controlling the flow of electrons between the cathode and anode using a control grid. When a small voltage is applied to the grid, it modulates the flow of electrons between the cathode and anode, leading to amplification of the input signal.

What is the evidence that show cathode rays consists of charged particles?
One piece of evidence is the observation that cathode rays are deflected by electric and magnetic fields, indicating they carry charge. Further evidence comes from the fact that cathode rays produce X-rays when striking a target, which is consistent with the behavior of charged particles like electrons. Additionally, the ratio of the charge to mass of the particles in cathode rays was found to be the same as that of electrons.
