How are AC vibrations converted to sound vibrations?
| October 23, 2020 | Education
A capacitor and a resistor are used to convert the current pulses into audio-frequency alternating current. Such values of the electrical capacitance of the capacitor and the electrical resistance of the resistor are selected, at which the capacitor is charged with each current pulse, but does not have time to completely discharge through the resistor in half the period of high-frequency oscillations and the voltage across the capacitor changes with an audio frequency.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
