What are quartz clocks?

Throughout history, people felt the need to know time. At first they just looked at the position of the sun. If it was in the middle of the sky, it was time for lunch. If it was dark outside, it was time to go to bed.

However, as cultures, technology and industry developed, a more accurate method of time management was required. As centuries passed, one relied on parasols, then for spring driven clocks or a shuttle clock. All these devices served their purpose, but both the pace of society accelerated, as well as the desire to know humanity's exact time. The answer was quartz clock. Inside the quartz hour you will find two very basic parts: quartz crystal and electronic oscillator. These two objects, if combined with different gears, engines and digital counters, allow average quartz clocks or watches to lose or get only ten seconds per year. They jumped into the mass popularity of the 70s. The years when technological progress has made is available. In addition to their accuracy and low cost Je beauty of quartz clocks in the materials of their own mineral, from which it gets a name.

quartz is incredibly common, located in sand and rock. However, it is unusual in that the quartz crystal is piezoelectric. This means that if a quartz crystal is vibrated or pressed, it will cause a very small electric current. In the same spirit, if someone should perform a small electric current over a quartz crystal, it would vibrate at a precise frequency. Even better, it would always vibrate at the same, exact frequency.

lies the secret of quartz clock. There is a small battery inside. Through the electronic circuit, electricity is fired through a quartz crystal. In response, the crystal begins to oscillate at exactly 32 768 times per second. Another electronion C calculates these vibrations and generates one pulse per second. Then sends this pulse to either a gear or a miniature engine that movesBelled with his hands around the face of the clock or converts information into a digital display.

Due to low energy consumption, batteries in a quartz watch or hours may take years. This is a great improvement that you have to remember that you remember how to wind your watch, estimate the length of shadows or stare at the sun. Thanks to quartz clocks you can now always be for lunch.
