General Physics 2023-2024 - Voltmeters, Ammeters, and Terminal Voltage | 17.3 General Physics

Chad provides a brief lesson on Voltmeters, Ammeters, and Terminal Voltage. The lesson begins by explaining that voltmeters measure the potential difference across a resistor in a circuit, are connected in parallel with that resistor, and that an ideal voltmeter has infinite resistance. Similarly, an ammeter measures electric current through a resistor, but in contrast, is connected in series with that resistor, and an ideal ammeter has zero resistance. The lesson concludes with an explanation of the internal resistance of a battery, and how that internal resistance results in the terminal voltage of the battery being lower than the emf of the battery. 00:00 Lesson Introduction 00:53 Voltmeters 02:31 Ammeters 06:10 Internal Resistance and Terminal Voltage Check out Chad's General Physics Master Course: https://www.chadsprep.com/physics-youtube #generalphysics #physicstutorial
