In this video we will be having a closer look at my wireless power coils in order to optimize them. That means I will show you exactly how to measure the most important characteristics of any coil and how to turn these values into the coil quality which I should keep as big as possible for my wireless power transmission. Along the way we will learn about LCR meters, how coils act at higher frequencies and ultimately (maybe) create my best wireless power coil so far. Let's get started!
