  2. Series and parallel circuits - Wikipedia

    en.wikipedia.org/wiki/Series_and_parallel_circuits

    A circuit composed solely of components connected in series is known as a series circuit; likewise, one connected completely in parallel is known as a parallel circuit. Many circuits can be analyzed as a combination of series and parallel circuits, along with other configurations .

  3. Series–parallel graph - Wikipedia

    en.wikipedia.org/wiki/Seriesparallel_graph

    Indeed, a graph has treewidth at most 2 if and only if it has branchwidth at most 2, if and only if every biconnected component is a series–parallel graph. [4] [5] The maximal series–parallel graphs, graphs to which no additional edges can be added without destroying their series–parallel structure, are exactly the 2-trees.

  4. Series and parallel springs - Wikipedia

    en.wikipedia.org/wiki/Series_and_parallel_springs

    The following table gives formula for the spring that is equivalent to a system of two springs, in series or in parallel, whose spring constants are and . [1] The compliance c {\displaystyle c} of a spring is the reciprocal 1 / k {\displaystyle 1/k} of its spring constant.)

    A converter consisting of two or more converter units parallel connected or series connected or both, each of which is an operative converter of its own. multiple connection (of commutating groups) A connection in which two or more identical commutating groups which do not commutate simultaneously are connected in such a way that their direct ...

  6. Randles circuit - Wikipedia

    en.wikipedia.org/wiki/Randles_circuit

    Randles circuit schematic. In electrochemistry , a Randles circuit is an equivalent electrical circuit that consists of an active electrolyte resistance R S in series with the parallel combination of the double-layer capacitance C dl and an impedance ( Z w ) of a faradaic reaction .

  7. Series-parallel - Wikipedia

    en.wikipedia.org/wiki/Series-parallel

    The expression series-parallel can apply to different domains: Series and parallel circuits for electrical circuits and electronic circuits; Series-parallel partial order, in partial order theory; Series–parallel graph in graph theory; Series–parallel networks problem, a combinatorial problem about series–parallel graphs

  8. Chemical reaction network theory - Wikipedia

    en.wikipedia.org/wiki/Chemical_reaction_network...

    Dynamical properties of reaction networks were studied in chemistry and physics after the invention of the law of mass action.The essential steps in this study were introduction of detailed balance for the complex chemical reactions by Rudolf Wegscheider (1901), [1] development of the quantitative theory of chemical chain reactions by Nikolay Semyonov (1934), [2] development of kinetics of ...

  9. Miller theorem - Wikipedia

    en.wikipedia.org/wiki/Miller_theorem

    It asserts that a floating impedance element, supplied by two voltage sources connected in series, may be split into two grounded elements with corresponding impedances. There is also a dual Miller theorem with regards to impedance supplied by two current sources connected in parallel.
