### Clocks digital and analog

All of electronics can be divided into two broad categories: analog and digital. One of the most common examples of the difference between analog and digital devices is a clock. On the analog clock, the time is represented by hands that spin around a dial and point to a location on the dial that represents the approximate time.

On a digital clock, a numeric display indicates the exact time. Analog refers to circuits in which quantities such as voltage or current vary at a continuous rate. When you turn the dial of a potentiometer, for example, you change the resistance by a continuously varying rate.

The resistance of the potentiometer can be any value between the minimum and maximum allowed by the pot. If you create a voltage divider by placing a fixed resistor in series with a potentiometer, the voltage at the point between the fixed resistor and the potentiometer increases or decreases smoothly as you turn the knob on the potentiometer. In digital electronics, quantities are counted rather than measured. When you count something, you get an exact result.

When you measure something, you get an approximate result. Consider a cake recipe that calls for 2 cups of flour, 1 cup of milk, and 2 eggs. To get 2 cups of flour, you scoop some flour into a 1-cup measuring cup, pour the flour into the bowl, and then do it again.

To get a cup of milk, you pour milk into a liquid measuring cup until the top of the milk lines up with the 1-cup line printed on the measuring cup and then pour the milk into the mixing bowl. To get 2 eggs, you count out 2 eggs, crack them open, and add them to the mixing bowl.

The measurements for flour and milk in this recipe are approximate. But the eggs are precisely counted: exactly 2. There will be exactly 2 eggs, because you count them. So which is more accurate — analog or digital? In one sense, digital circuits are more accurate because they count with complete precision.

You can precisely count the number of jelly beans in a jar, for example. Say that the needle on the scale is about halfway between 4 pounds and 5 pounds.

Does the jar weigh 4.Teachers Pay Teachers is an online marketplace where teachers buy and sell original educational materials. Are you getting the free resources, updates, and special offers we send out every week in our teacher newsletter? Grade Level.

A clock happens to be one of the oldest inventions around and hence has evolved over the years. There are many types of clocks available in the markets. However, the question is whether to go for analog or digital. There are many types of clocks and not every clock fits every room. For example, a nice designer skeleton wall clock will not fit in a traditional living room.

### Compare and Contrast Clocks

Some may prefer to search for an antique or contemporary wall clock in Australia. Let us understand the difference between Analog and Digital Walls and know about the factors that you should look into while selecting a Wall Clock. This is one of the first decisions to make. Some prefer to see the time in digits while others prefer the traditional clock face with the minute and the hour hands.

Besides personal preference, there are many pro and cons of using both. A digital watch has the ability to set itself automatically, either via the Internet or using the atomic time; this is not so for an analog clock. A digital clock usually works on the mains power and will turn off if there is a power outage. Such clocks will usually maintain the time but will not display it in this case.

The advantage of an analog clock is that a power outage will not affect it. An analog clock tends to be noisier as well since most of them will have a ticking sound. The ticking in an analog clock is a constant sound at a regular frequency.

It may be possible to find a non-ticking analog clock however; a majority of them will have a sound. A clock is of value only if it keeps time. An atomic clock frequently synchronizes the time and hence is likely to be accurate at all times. An analog clock may not necessarily keep time especially if it is a mechanical one.What do you want to do?
