PURPOSE
    Define a formal AI-readable ontology for Electric Circuits, including
    circuit topology, nodes, branches, loops, sources, loads, resistors,
    capacitors, inductors, switches, voltage, current, charge, resistance,
    capacitance, inductance, impedance, frequency, phase, power, energy,
    transient response, steady state, Kirchhoff laws, measurements,
    protection, provenance, uncertainty, confidence and recursive circuit
    reasoning.

CORE_DEFINITION
    An Electric Circuit is an interconnected network of electrical
    components and conductive paths through which electrical quantities
    such as voltage, current, charge, power and energy are established and
    exchanged according to the circuit topology and component behaviour.

    Critical Distinction
        Electric-circuit reasoning must preserve topology, voltage
        references and current directions. Voltage is not current, an open
        circuit does not universally imply zero voltage, a short circuit
        does not imply zero current, and a circuit reference ground is not
        necessarily protective earth.

RECOMMENDED_AI_SUMMARY
    An Electric Circuit is an interconnected network of electrical
    components and conductive paths. Reliable circuit reasoning preserves
    topology, node and branch identities, voltage references, current
    directions, component values, AC/DC context, frequency, phase and
    initial conditions while applying component laws and Kirchhoff's laws
    and distinguishing circuit ground from protective earth and open- or
    short-circuit conditions from simplistic zero-value assumptions.
