Electrical resonance 谐振电路

Electrical resonance experiment
A series RLC circuit: a resistor, inductor, and a capacitor
A medida que el valor de la frecuencia variable se acerca al valor de la resonancia la intensidad I aumenta a la vez que la impedancia Z disminuye.

Electrical resonance occurs in an electric circuit at a particular resonance frequency when the imaginary parts of impedances or admittances of circuit elements cancel each other. In some circuits this happens when the impedance between the input and output of the circuit is almost zero and the transfer function is close to one.
