The major supply of electrons in an electron tube; in immediately heated tubes the filament is the cathode, and in not directly heated tubes a coated metallic cathode surrounds a heater. Designated K. Also often known as adverse electrode. The terminal at which present leaves a major cell or storage battery; it’s negative with respect to the device, and optimistic with respect to the exterior circuit. The electrode of an electrolytic cell, an electrical arc, and different related gadgets which might be linked to the negative pole of a source of current. Light enters the cell by way of the transparent anode, and is absorbed within the bulk heterojunction layer via generation of excitons .
In particular, for a LED show module, the so-known as common-anode configuration would extra properly be referred to as the frequent-P-facet configuration. Although anode and cathode are basically defined in terms of perform not structure, … Read MoreRead More »
