Electrical circuit topology

a) branch - a section of an electrical circuit with the same current

branch is active


branch passive


The number of branches - p
b) a node - q a junction of three or more branches; nodes are potential or geometric
rice one

Four geometric nodes (abcd) and three potential (abc) as the potentials of nodes c and d are equal:
φс = φd

c) Contour - a closed path passing through several branches and nodes of an extensive electrical circuit - abcd, fig. 1. An independent circuit with at least one new branch.

d) Bipolar - part of an electrical circuit having two poles of the output. Bipolar networks are active and passive.

e) Four - port network - a part of an electrical circuit having four poles of a terminal, are active and passive.
