Kondensatory, pojemność, jak działa

In this video, I explain what a capacitor is and how it works. I present an animation showing the first capacitors and their history. I demonstrate their structure and how charges flow. I demonstrate an experiment with charging and discharging a capacitor, which is consistent with the high school curriculum. I present the formulas for the stored energy in a capacitor and for the capacitance of a capacitor. You will learn how charge and applied voltage are related to the capacitance of a capacitor. 00:00 Introduction to Capacitors 00:32 How Were Capacitors Invented? 00:55 What is a Leyden jar and where was it discovered? 01:15 How is a Leyden jar constructed? 01:36 Conspiracy theories about ancient light bulbs 01:47 Animation showing an improved Leyden jar 02:22 Parallel plate capacitor - structure and principle of operation 03:06 Formula for the electric field strength of a capacitor 03:17 Capacitor energy - where is it stored? 04:02 Capacitor capacitance - what is it? 04:22 What determines capacitor capacitance? 04:52 What does a capacitor look like today? 05:20 How do capacitor capacitance and voltage affect the stored charge? 05:40 What does a capacitor look like in a diagram? 05:49 Charging a capacitor - experiment 06:20 Experiment showing energy dissipation by a capacitor 06:30 Calculating the field strength between the plates of a parallel plate capacitor 06:54 Everything you need to know about a capacitor in one picture. #physics #capacitor #capacitance
