Question

define cathode and it's uses in our day to day life​

Answer 1

Answer:

Most electrons (cathode rays) hit the anode and are drawn off as an electrical current but some pass through a small hole and shoot past the electrode forming a beam of electrons (cathode rays) which can be used in displays (such as the old CRT TVs, monitors and oscilloscopes) or to produce x-rays.

Answer 2

Answer:

The cathode ray tube (CRT) is a vacuum tube containing one or more electron guns (a source of directed electrons) and a fluorescent screen used to view images. It has a means to accelerate and deflect the electron beam onto the fluorescent screen to create the images.

The cathode ray tube (CRT) is a vacuum tube containing one or more electron guns (a source of directed electrons) and a fluorescent screen used to view images. It has a means to accelerate and deflect the electron beam onto the fluorescent screen to create the images.In general, the anode is the electrode that positive current flows INTO from the outside, and the cathode is the electrode that it flows FROM (to the outside). Electrons, of course, flow the opposite way. In electrochemistry, the anode is where oxidation occurs and cathode is where reduction occurs ("an ox red cat").
