  2. Circuit diagram - Wikipedia

    en.wikipedia.org/wiki/Circuit_diagram

    Once the schematic has been made, it is converted into a layout that can be fabricated onto a printed circuit board (PCB). Schematic-driven layout starts with the process of schematic capture. The result is what is known as a rat's nest. The rat's nest is a jumble of wires (lines) criss-crossing each other to their destination nodes.

    Quantum Physics, by Eyvind H. Wichmann; Statistical Physics, by Frederick Reif; Volume 2, Electricity and Magnetism, by Purcell (Harvard), is particularly well known, and was influential for its use of relativity in the presentation of the subject at the introductory college level. Half a century later the book is still in print, in an updated ...

    Figure 1.2. Series and parallel topologies with two branches. Even for these simplest of topologies, the circuit can be presented in varying ways. Figure 1.3. All these topologies are identical. Series topology is a general name. Voltage divider or potential divider is used for circuits of that purpose. L-section is a common name for the ...

    [1] [2] [3] An example of a scalar field is a weather map, with the surface temperature described by assigning a number to each point on the map. A surface wind map, [4] assigning an arrow to each point on a map that describes the wind speed and direction at that point, is an example of a vector field, i.e. a 1-dimensional (rank-1) tensor field ...
