What is a quartz watch? .

You may have read the word quartz written on the dial of many watches. Do you know what this quartz is? When the clock was invented, keyed clocks were used for years. Quartz is a substance called silicon dioxide. It is a magical substance that can withstand a lot of heat. When an electric current is applied, the electrode remains on its surface and the current causes a certain amount of change on its surface. The surprising thing is that when this quartz is arranged in a bright position, it itself produces an electric current, which is called the piezo electric effect.
