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

 

The best way to connect a trimmer capacitor in an RF circuit

 

Testing a parallel tuned circuit

 

Two tricks with tuned circuits

 

Experiments with a biscuit tin cavity filter for UHF

 

Testing materials for RF properties with a simple receiver

 

You can learn more about inductors, capacitors and tuned circuits via the following references:
