A significantly expanded 14-page chapter for AP Physics C. It includes detailed sections on the nature of Ohm's Law as an empirical relationship, a professional I-V characteristic curve diagram for Ohmic and Non-Ohmic components, and the concept of differential resistance. Content on temperature dependence has been removed to focus on structural and material origins of resistance.

An extensive 12-page chapter for AP Physics C on current electricity. It includes the Drude model of conduction, physical scattering mechanisms of resistance (with diagram), and high-level calculus-based network analysis, while removing temperature dependence as requested.

Updated teacher guide to reflect the expanded 7-page reading chapter and revised instructional flow timings for the Circuit Mastery lesson.

Detailed answer key for the Circuit Mastery problem set, including full calculus derivations and numerical solutions for the Kirchhoff network analysis.

An advanced problem set for AP Physics C covering variable resistivity derivation, multi-loop Kirchhoff analysis, and the Maximum Power Transfer Theorem derivation using calculus.

Updated guided note-taking worksheet to match the 7-page reading chapter, ensuring section references for Kirchhoff's Rules and sign conventions are accurate.

An expanded 7-page reading chapter for AP Physics C on current electricity. It includes new professional SVG diagrams for a simple circuit (Fig 24.1) and microscopic drift velocity (Fig 24.2), maintaining high technical rigor without condensing the text.

Updated teacher reading script for the Station 4 Listening activity, now including instructions for placing a bridge (straight line) and parks (circles).
