"Cathode" Examples

Cathode

A cathode is a negatively charged electrode or plate.

Examples:

In a battery, the cathode is the positive terminal where the chemical reaction occurs to produce an electric current.
Example sentence: "The cathode of the battery is where the oxidation reaction takes place, releasing electrons."
In an X-ray tube, the cathode is the negatively charged electrode that produces a beam of electrons.
Example sentence: "The cathode is heated to produce a beam of electrons that produces X-rays when they interact with the anode."
In a vacuum tube, such as a television tube, the cathode is the electrode that emits electrons to create an electron beam.
Example sentence: "The cathode of the TV tube is the source of the electron beam that scans the phosphor coating to produce the image on the screen."
In some electrolysis cells, the cathode is where reduction occurs, releasing Hydrogen gas.
Example sentence: "At the cathode of the electrolysis cell, hydrogen ions are reduced to release hydrogen gas, which is then collected."
In some medical devices, such as dialysis machines, the cathode is used to produce a gentle electric current to facilitate water removal.
Example sentence: "The cathode of the dialysis machine produces a gentle electric current that helps remove excess fluid from the patient's body."
