What this subsection covers
Charge conservation at nodes, signed branch currents, steady-state assumptions, equation independence, and measurement checks.A strong response uses labelled multi-loop circuits and states where the model stops being reliable.
Reasoning checklist
Evidence, assumptions and limits
Assumptions to state
State the system, observable, approximation, and conditions held fixed before using a model.
Evidence to collect
Do measured branch currents and loop voltages satisfy both conservation rules within uncertainty?

Do measured branch currents and loop voltages satisfy both conservation rules within uncertainty? Useful evidence includes calibrated current and voltage measurements, junction sums, loop sums, propagated uncertainty, and discrepancy analysis.

This GioPhysics course map is an adaptable learning sequence, not academic credit, accreditation, or a universal university syllabus. Departments may redistribute weeks, laboratory hours, optics, or the modern-physics survey to match local requirements. Thermal physics appears as an unnumbered institutional extension: some universities assess it within Physics II, while others teach it in a separate course, so include the thermal extensions only where the local syllabus requires them. A result should be checked against units, signs, limiting cases, and the conditions under which its model was derived.
