What is a cathode tubes?
A type of vacuum tube that forms an electron beam (aka cathode ray) instead of just a diffuse cloud of electrons. There are literally millions of kinds of cathode ray tubes designed for various purposes:x-ray tubepicture tubevidicon tubeiconoscope tubeimage orthicon tubeimage dissector tubewilliams tube (a type of DRAM used in early computers)oscilloscope tubegraphechon tube (a dual CRT used for video scan conversion, e.g. 50Hz frames to 60Hz frames, circular radar scan to rectangular scan)etc.
Explain what a dry cell battery is?
There are two conductors were electricity begins and runs through wires which make energy come out of a battery. <<>> In the center of each cell there is a rod called a cathode. It is usually composed of graphite. Surrounding this cathode there is an electrolytic substance which acts as a medium to conduct electricity. The cathode and electrolytic substance are separated from the outer container by a cardboard tube. This assembly is sealed into a metallic cylinder. In older type batteries this cylinder was made of zinc. This part of the battery is known as the anode. When a load is connected between the cathode (+) and the anode (-) terminals, a chemical reaction takes place between the cathode and the electrolytic material. This chemical reaction generates a 1.5 volt potential between the two terminals.
I don't understand. What are anodes and cathodes Positive or Negative I keep seeing different answers everywhere Thanks.?
It can be complicated depending on the type of cell one is looking at. However, here is my simple explanation.The anode is the electrode where the oxidation reaction takes place, and oxidation is the loss of electrons, so in a galvanic cell the anode is a source of free electrons and so it is negatively charged.The cathode is the electrode where reduction takes place, and reduction is the gain of electrons, so in a galvanic cell the cathode is positively charge and ready to accept negatively charged electrons.Now, the anode isn't always negative and the cathode isn't always positive. It has to do with the direction of current flow (anode = current in, cathode = current out). In an electrolytic cell, the charges on the anode and the cathode are reversed from that seen in a galvanic cell.
What is the filament used in tubelight-?
The type of filament used in tube light is that one which is thin and surrounded by an oblong metal shield.
What is paper plate made from?
A thin type of cardboard which is made from trees.
Which type of motion does cathode rays create?
Cathode rays create straight-line motion. They are streams of electrons that travel in a straight line from the cathode to the anode in a vacuum tube.
Why did Thomson see cathode rays with every element?
Thomson observed cathode rays with every element because cathode rays are composed of electrons, which are fundamental particles present in all atoms regardless of the element. When a high voltage is applied in a vacuum tube, electrons are emitted from the cathode and accelerate toward the anode, creating cathode rays. This universal presence of electrons in all elements allowed Thomson to consistently detect cathode rays across different materials. His experiments demonstrated that these rays were not dependent on the type of gas or metal used in the cathode.
Why cathode ray are not electro-magnetic waves?
A cathode ray is a stream of electrons, not a stream of photons like the electromagnetic wave. It's a different type of particle. The electrons don't move at light speed in a vacuum; also, they are electrically charged.
What are in Proton rays?
Proton rays consist of protons, a type of positively charged atomic particle, rather than photons, which have neither mass nor charge
What is a cell lithium ion?
It is a type of battery that can be recharged in which the anode contains lithiam and the cathode is made of a type of porous carbon.
What is a lithium-ion cells?
It is a type of battery that can be recharged in which the anode contains lithiam and the cathode is made of a type of porous carbon.
Who performed the cathode ray experiment which led to the discovery of the electron?
Crookes observed that the cathodic rays are deflected by a magnetic field and concluded that this beam is negatively charged. Thomson established that the beam is composed from a new type of particles called by Fitzgerald electrons. Thompson also believed that electrons float in a "pudding" of positive charges.
What type of screws are recommended for assembling furniture made of particle board screws?
For assembling furniture made of particle board, it is recommended to use coarse-threaded screws.
How are gamma rays produced?
Gamma rays are produced by high-energy processes such as nuclear reactions, supernovae explosions, or particle interactions. These processes release immense amounts of energy, causing some of it to be emitted in the form of gamma rays, which are the most energetic type of electromagnetic radiation.
Design and complete a concept map using element anode cathode electron alpha particle proton neutron electron cloud?
Sure, here is a concept map for you: Anode: positive electrode in an electrical cell where oxidation occurs Cathode: negative electrode where reduction takes place Electron: negatively charged subatomic particle found in atoms Alpha particle: a type of nuclear radiation consisting of two protons and two neutrons Proton: positively charged subatomic particle found in atomic nuclei Neutron: neutral subatomic particle found in atomic nuclei Electron cloud: region around the nucleus where electrons are likely to be found
Type of rays that come together?
The type of rays that come together are called convergent rays.
What is a crookes tube?
A Crookes tube is a type of cathode ray tube that was used for scientific experiments and demonstrations in the late 19th century. It consists of a partially evacuated glass tube with electrodes that generate a beam of electrons. This device played a pivotal role in the discovery of cathode rays and led to the development of modern television and computer displays.
