Question

Quizplus · Accepted Answer

The system clock uses a vibrating quartz crystal to keep time accurately. When an electric charge is applied to this crystal, it vibrates at a precise frequency (usually 32,768 times per second) that can be used to mark time intervals. This makes quartz crystals highly accurate and reliable for timekeeping purposes. Lithium batteries are often used to power electronic devices, but they are not directly involved in timekeeping functions. There is no such thing as a vibrating lithium crystal.
