Electrical and electronic equipment: what's the difference?

Electrical and electronic equipment: what's the difference in electrical and electronic equipment not just two names for the same! Mechatronics Engineer Michael Chandler explains the differences.

Electrical and electronic equipment may sound similar, but they are very different. Both involve moving electricity in a circuit to useful products and machines, but that's where the similarity ends!

How do they work?
The main difference between the electrical and electronic circuits in electric circuit do not have a decision-making process (process) opportunity, while electronic circuits do circuitry just powers the machine with electricity. However, electronic circuit might interpret the signal or command, and perform the task under the circumstance. For example, microwave often bleeps when it has finished Cook to tell the user that his or her food is ready.

The majority of modern devices use a combination of electric and electronic circuits. washing machine has a circuit that contains power socket, fuse, switch the on/off switch, the heater and the engine that spins the drum. The desired wash cycle and temperature are entered by the user through the control panel. These instructions are interpreted by using electronic circuits that were designed and programmed to understand that you would like based on what buttons were pressed. When the electronic circuit interprets these commands it sends signals in electrical control circuit heater and engine heat and spin the drum, for the time necessary.

The difference of scale
Most of the electronic components is very small, and requires a small direct current (DC) voltage. a micro-processor that will fit on the end of your finger, can contain hundreds or thousands of tiny components, some of which are only a few atoms wide! Electrical components, usually more, and use alternating current (AC) voltage. Despite the fact that most electronic components run on 3-12 volt DC electrical devices require 230 volts AC. Factories and power plants, however, can require up to 11000 volts and most electricity journey throughout the UK at 400000 volts!

Some products, such as computers, have much more than electronic components electrical components. Large industrial sites, such as factories and power plants, however, are much more electrical components.

How do they work together?
Relationship between electronic and electrical circuits, as a rule, the relays or transistors. They are essentially switches, but, rather than pushed manually, like a light switch, are run by small shock from an electronic circuit. So a small circuit-often with lots of small components-can be used for much more electrical equipment. It makes use of household and industrial products safe, and means they are smaller and more energy efficient.

Relay is a mechanical device that, when a small current passes from the electronic circuit, metal contactor closes an electrical circuit, allowing much more current to pass through. Relays were, however, large and unreliable, and usually require a lot of current. After repeated use, the moving parts wear out and cease to function properly. Transistors, however, may be much less and require a very small amount of current, and have no moving parts. the transistor was invented in 1948, and, perhaps, the most important invention in the past 100 years.
