Electronics is the study of weak current electrical devices that operate by controlling the flow of electrons or electrically charged particles in a device such as computers, electronic equipment, thermocouples, semiconductors, and so forth. The study of such tools is a branch of physics, while the forms design and manufacture of electronic circuits is part of electrical engineering, computer engineering, and science / electronics and instrumentation engineering.
Tools that use the basic electronics work is usually referred to as electronic appliances (electronic devices). Examples of equipment / electronic devices are: Cathode Ray Tube (Cathode Ray Tube, CRT), radios, TVs, cassette recorders, video cassette recorder (VCR), recording VCD, DVD, load speakers, freezer, washing machine, mp3, recorders, video cameras, digital cameras, desk-top personal computers, Laptop computers, PDAs (pocket computers), , robots, smart cards, etc..
