Direct Current Circuits: Kirchhoff's Laws and Resistors

This lecture covers the conditions for the written exam, including allowed materials and prohibited items. It then delves into the concepts of DC currents, resistors, and capacitors, exploring Ohm's law, resistance, and resistivity values. The Drude model, Kirchhoff's laws, power in DC circuits, and electromotive force generators are also discussed. The lecture further examines network analysis, capacitors in DC circuits, and temperature-dependent conductivities. Imperfections in real crystals and the Drude model's formulas are explained, along with electrical conductivities and temperature dependencies. Finally, the lecture introduces electromotive force in DC circuits, Kirchhoff's laws, and the concept of resistors in electric circuits.
