Most of us only think about our clocks when the alarm goes off, we are late, or we need to know the time. We probably never think about how they work. In fact, the only time we How they work, or do not work, is probably a mystery. But, electric and digital clocks are very reliable. There are very few parts, and those parts do not have much wear and tear. Although they are running nearly all the time, they run very efficiently,and smoothly.
An electric clock is probably one of the most reliable motors. The small motor uses very little electricity. The clock relies on 60 cycle-per-second alternations of current to maintain time. The clock is made of a case to hold the motor, the motor, a time-set knob, alarm lever, alarm mechanism, gear assembly, dial light, face, hands, some type of covering, and the power cord.
An electric clock works because the motor turns gears, which in turn, move the clock hands. Some clocks have metal gears, while others have plastic. Plastic gears tend to be quieter, and are used by most modern manufacturers.
Digital clocks rely on electronic circuitry, instead of gears. Electricity powers an electronic control panel, which posts the time. While they work well, they are difficult to fix. If you have problems with your digital
clock, you will likely have to replace it.
Digital clocks also must be set, and will need to be reset with a break in power. Electric clocks will stop without power, but will continue time, when power is restored. If you have returned home, and the power has been out, this is why some of your clocks might be flashing, while others are off, but still going.
