Digital and Analogue Clocks

Digital clocks work by transforming electrical signals and electrical power into a readable time display. The internal clock of the device is powered by a battery, and an oscillator generates a series of electrical pulses that are used to keep time. The power of the battery also displays the time kept by the electrical pulses on a screen.

Most modern analogue clocks use quartz to keep time. When quartz receives a large enough amount of energy from the battery of the mechanism, the quartz vibrates. This is what causes the hands to move and make the "tick-tock" noise.

Similarities:

• • Both modern versions of the clocks use batteries or electricity to power them.

  • Both keep the time very accurately

Differences:

• Digital clocks display the time with a display screen

• Analogue clocks display the time with hands

• Digital clocks use an oscillator that generates electric pulses to keep the time

• Analogue clocks use quartz to keep the time correct
