Electric Circuits: Current, Resistance, and Power

This lecture covers the fundamental concepts of electric circuits, including electric current, resistance, and Ohm's law. The instructor explains the behavior of electrons in a conductor, the generation of electric fields, and the Joule effect. The lecture also delves into the power dissipation in circuits, the use of ammeters and voltmeters, and the application of Kirchhoff's laws. Additionally, the charging and discharging of capacitors in RC circuits are explored, along with the concept of electrical resistance. Practical experiments on Ohm's law and Kirchhoff's laws are demonstrated.
