How is a quartz crystal used in electronics?

The quartz crystal used in a Quartz Crystal Oscillator is a very small, thin piece or wafer of cut quartz with the two parallel surfaces metallised to make the required electrical connections. read more

Crystal is the common term used in electronics for the frequency-determining component, a wafer of quartz crystal or ceramic with electrodes connected to it. A more accurate term for it is piezoelectric resonator. read more

Quartz crystal applications. Quartz crystals are used in two main forms of applications, namely as the resonant element in oscillators, and they are also used in filters. In both applications the very high Q of the resonator enables very high performance levels to be achieved. read more

Quartz is used as a piezoelectric cell which produces electricity when applied stress and even has converse effect.. for eg quartz is used in earphones where it uses the inverse piezoelectric effect, where mechanical vibrations(sound) are produced when supplied with electicity. read more
