Inductors, capacitors and tuned circuits You pretty much don't have radio without inductors, capacitors and the tuned circuits they form when connected. These videos explain a little about these parts and some tricks you can do with them.   Demonstrating Capacitance, Inductance, Reactance and Frequency   Lower capacitance from a two gang variable capacitor   What to do if they stop making variable capacitors   Calculate tuned circuit values in your head   A look at frequency reactance nomographs   The best way to connect a trimmer capacitor in an RF circuit   Testing a parallel tuned circuit   Two tricks with tuned circuits   Low pass filters: How one capacitor can make a big difference   Experiments with a biscuit tin cavity filter for UHF   Testing materials for RF properties with a simple receiver   Calculating tuned circuit values in your head   Disclosure: I receive a small commission from items purchased through links on this site.
