Lecture
This lecture delves into the microscopic aspects of resistance, focusing on the physics behind bad conductors and the scattering of charge carriers, leading to Ohm's law. The analysis extends to circuits with resistors, capacitors, and electromotive forces, culminating in a full network analysis. The instructor explains the concept of drift motion, the role of thermal energy in charge carrier movement, and the temperature dependence of conductivity. The lecture also covers the dual model, Kirchhoff's laws, and power consumption in circuits, emphasizing the relationship between Ohm's law and the microscopic picture of resistance.
