A cathode is a negatively charged metal electrode from which conventional current travels in a polarized electrical device. It attracts positive charge or cations. The behavior of the cathode is the opposite to that of an anode. In a polarized electrical device, a cathode is considered the electr...
An air cathode is a device that conducts oxygen into an electrolyte to generate an electrical current. It's most commonly used for...
A cathode-ray tube (CRT) is a specialized vacuum tube in which images are produced when anelectronbeam strikes a phosphorescent surface. Most desktop computerdisplaysmake use of CRTs. The CRT in a computer display is similar to the "picture tube" in a television receiver. A cathode-ray tube...
A typical red cathode CCFL transmits light at a spectral energy distribution between about 570 to 700 nanometers (nm), with its mean at about 630 nm; that is, it's a wider and more yellowish bell curve on the light spectrum. One variation is the deeper, ruby red wavelength, with a ...
Tool used for measuring the voltage of the cathode-ray tube inside of your computer CRT (Cathode Ray Tube) monitor. The cathode ray oscilloscope was invented by German scientist Karl Ferdinand Braun in 1897.Related information Computer monitor help and support....
What is a light-emitting diode (LED) backlit display? An LED-backlit display is a type of LCD display that uses LEDs to illuminate the screen. It offers better energy efficiency, thinner form factors, and improved color reproduction compared to traditional cold cathode fluorescent lamp (CCFL) ...
What is an Air Cathode? What are the Basics of Anode Voltage? What is Hot Cathode? What is a Copper Anode? Discussion Comments BySkyWhisperer— On Aug 01, 2011 @Mammmood - I wouldn’t waste time with the alkaline battery chargers myself. From what I’ve read you never really get th...

Every type of battery operated during discharge is a voltaic cell. The oxidation half-reaction will occur at the anode half-cell, while the reduction half-reaction will occur at the cathode half-cell. Phases are included in the respective equations and the numbers of electrons are balanced...
What is an LFP Battery? An LFP battery gets its name from it’s key material component, lithium iron phosphate powder, which has the chemical formula LiFePO4. It is also known as lithium ferro phosphate which gets shortened to LFP, hence the name. ...
