Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain electrical circuits and their elements, relay circuit theory and analysis methods, describe how circuits are built on boards and chips, and relay safety and standards.

An interconnection of electrical components such as sources, resistors, capacitors, inductors, switches, semiconductors and integrated circuits forming a closed path through which current can flow, realised as wiring, printed circuit boards or integrated circuits on semiconductor substrates; circuits range from a battery and lamp to complex electronic systems, are analysed by circuit theory and built to standards for safety and performance.

What it is for: Controlling and using electric current.

It can be explain elements and topology; relay analysis methods; describe construction on boards and chips; relay safety and standards.

Distinguishing features

Closed conducting path

Passive and active elements

Analysed by laws such as Kirchhoff

Built at scales from wiring to chips

What it looks like

Components connected by wires or traces on a board, or microscopic structures on a chip.

How it is recognised

Closed path for current through components

Wired, printed and integrated forms

A circuit diagram represents it; a network in the abstract is its model

What the second pass must settle

  • How should standards be linked?
  • The registry entry has merged aliases naming IC series, boards and protection devices; should they be split off?
