VARIABLE condensers are now so commonly employed in radio receivers to tune circuits including a constant inductance that the use, some years ago, of variable inductances or variometers with fixed ...

A special frequency determined by the values of the resistance, capacitance and inductance refers to the resonance in AC circuits. The resonant frequency point occurs where the inductive reactance of ...

A tuned circuit formed by a capacitor and an inductor is a familiar enough circuit, and it’s understood that it will resonate at a particular frequency. As that frequency increases, so the size of the ...
