värähtelypiiri
Värähtelypiiri, also known as a resonant circuit or tuned circuit, is an electrical circuit that can oscillate at some specific frequencies. These frequencies are determined by the circuit's components, typically an inductor (L) and a capacitor (C). The fundamental principle behind a värähtelypiiri is the exchange of energy between the inductor's magnetic field and the capacitor's electric field.
When a voltage is applied, the capacitor charges, storing energy in its electric field. As the capacitor
The natural resonant frequency (f0) of an ideal LC värähtelypiiri is given by the formula f0 = 1
Värähtelypiirit are fundamental components in many electronic applications. They are used in radio receivers and transmitters
