The good electrical conductivity of plasmas makes their electric fields very small. This results in the important concept of quasineutrality , which says the density of negative charges is approximately equal to the density of positive charges over large volumes of the plasma ( n e = Z > n i ), but on the scale of the Debye length there can be ...
The galvanic series (or electropotential series) determines the nobility of metals and semi-metals.When two metals are submerged in an electrolyte, while also electrically connected by some external conductor, the less noble (base) will experience galvanic corrosion.
Non-oriented electrical silicon steel (image made with magneto-optical sensor and polarizer microscope) Electrical steel made without special processing to control crystal orientation, non-oriented steel, usually has a silicon level of 2 to 3.5% and has similar magnetic properties in all directions, i.e., it is isotropic.
An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit. These symbols are largely standardized internationally today, but may vary from country to country, or engineering ...

Size comparison of axial-lead resistors. A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages , bias active elements, and terminate transmission lines , among other uses.
