Why is quartz good for working watches and other electronic machines?
Quartz is a piezoelectric material. This means that it vibrates when current is passed through it. It also means that when it is vibrated or put under pressure, it generates current. When current is passed through a quartz element, it vibrates, which in turn puts some current back into the circuit. This creates a feedback look that creates a waveform in the electrical signal; this wave can then be used as a clock by using electronic components to measure the number of wave cycles that have passed. This means that quartz is an integral part of any timing circuit, and timing is important for watches, computers, and anything that requires coordination between different parts.

Thanks for the feedback!
a computer is a programmable machine while eletronic component is any physical entity in aneletronic system
It works by using the piezoelectric effect: if a small voltage is applied to a specially prepared crystal of quartz it vibrates at a definite and almost constant frequency whi…ch can be used to power a tiny motor to turn the hands of the watch.
Weight is sensed using a transducer. A weighing machine transducer is usually a spring/piezoelectric component. The resistance of it varies as the weight changes. So does the …current through it. This current is sensed, and is converted suitably to output it's weight.
The liquid inside gathers info from a magnetosphere!
\nIt scratches a thin layer of the surface off whatever is being etched, and leaves a pattern behind which differs from the smooth surface, revealing the design.
I would guess a Supervisor.. overseer?
No, mechanical and automatic watches are powered by a mainspring, quartz watches are powered by a battery. A mechanical watch needs to be manual wound by the crown and is lack…ing a rotor. An automatic watch is wound by a rotor that tightens the mainspring, it can also be manually wound by the crown.
i must not drop it,not eat it lol
Quartz and mechanical watches use vastly different technology to power movements. A quartz crystal watch uses a tiny battery to electronically power the movement. A mechanical… watch uses a balance wheel and hairspring. Hand-winding the mechanical watch powers the movement. For more information please refer to the related link below:-

Many analogue watches nowadays use what's called a piezo-electric crystal to generate the energy required to function. In essence a piezo-electric crystal will generate an ele…ctric current when it is deformed, which can be achieved simply by applying a force to it (such as the one generated by the movement of your arm when you're wearing the watch). Recently, Nokia patented the first self-charging mobile phone, which uses the same principles in order to charge itself.
Practically every electronic machine, from vacuum cleaners to electric cars, use magnetism to work. This is because, with very few exceptions, the electromagnetic energy of th…e circuits within electronic machines is converted into usable mechanical energy by an electric motor, and most electric motors operate by using the following property found in electromagnets: a moving electric charge in an electromagnet, like a current, produces a magnetic field.
Quartz has the property of being piezo electric. It can bend with electricity or produce electricity by bending. Cutting a quartz crytal to precise dimensions will allow it it… resonate when stimulated. Electronics in the watch use the crystal in an oscillator circuit to produce a frequency, typically 32,768Hz. This can be divided down using electronic counters, to give one pulse every second. In an analogue watch, this one pulse is applied to a stepper motor which moves the second hand, one second. Gears from the second hand drive the minute and hour hands like a conventional watch. Digital watches use an LED or LCD display, driven by counter circuits that advance one second at a time.
Study the electronic voting machine and for free you can make a working model. Mechanical skills and direction following is required. Use old parts laying around to build the …model and this will cut out any cost.
