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 ...

There have been many different ideas presented for increasing the acoustic output of a piezo buzzer or ultrasonic transducer. Most of them involve rather complicated circuitry that drives up the total ...

Wireless power transfer (WPT) enables device charging without direct physical or wired connections. Resonant circuits are key components of WPT systems that optimize energy transfer from the ...
