Analog wall clock

Most homes have at least one clock. People in the home use clocks to know when things will occur or when they need to do something to prepare. Clocks track time and are incorporated into other devices that require things to happen at a certain time, like DVRs or alarm clocks and into other devices that need to operate for a set time period, like a microwave oven.

Some clocks are powered by being plugged into the electrical system; others run on batteries
