Electric Circuits: DC Circuits

This lecture covers the analysis of DC electric circuits, focusing on the relationship between voltage, current, and power in a circuit with a generator and a motor. It explains the concept of electromotive force, internal resistance, power dissipation, and efficiency in the context of electrical machines. The lecture also introduces the use of ammeters and voltmeters to measure current and voltage in circuits, emphasizing their proper placement and resistance. Through examples and calculations, students learn how to determine power distribution and efficiency in DC circuits.
