Kurz erklärt: Innenwiderstand, Leerlaufspannung, Kurzschlussstrom | Lerne Elektronik

🎓Learning material for the video: https://go.tfe.academy/21020440 In this video, you'll learn why ideal voltage sources, like those regularly found in circuit diagrams, don't exist in practice and what you need to consider when powering a circuit with a battery. By the end of the video, you'll know what the terms internal resistance, short-circuit current, and open-circuit voltage mean, and how to quickly and easily compare two batteries. And at the end, as always, there's a summary of the most important facts from the video. So, it's worth staying tuned! -------- CONTENT 0:34 Why do we need substitute quantities for real voltage sources? 4:12 The open-circuit voltage 6:33 The short-circuit current 8:36 Example comparison of two batteries 9:54 Summary of the characteristics of real voltage sources -------- LINKS Podcast "Electronics and Programming": https://go.tfe.academy/podcast Electrical engineering and electronics: https://go.tfe.academy/elektronik Programming & interface topics between electronics and computer science: https://go.tfe.academy/programmieren Conversations with interesting personalities from the STEM field: https://go.tfe.academy/talk -------- ABOUT Andreas Haja works as a professor at the Emden/Leer University of Applied Sciences and has been involved in engineering education for several years. The goal of his channel, "Electronics & Programming," is to convey theory and practice in a way that combines learning with fun and curiosity. Studying in the 2020s can be so much more than the classic frontal lecture of the past few centuries! https://www.thefearlessengineer.com
