Interstellar nebulae Complex plasma phenomena[ edit ] Although the underlying equations governing plasmas are relatively simple, plasma behaviour is extraordinarily varied and subtle: Such systems lie in some sense on the boundary between ordered and disordered behaviour and cannot typically be described either by simple, smooth, mathematical functions, or by pure randomness.
The word electronics is derived from electron mechanics, which means to study the behavior of an electron under different conditions of applied electric field.
Electronics definition The branch of engineering in which the flow and control of electrons in vacuum or semiconductor are studied is called electronics. Electronics can also be defined as the branch of engineering in which the electronic devices and their utilization are studied.
The motion of electrons through a conductor gives us electric current. This electric current can be produced with the help of batteries and generators. The device which controls the flow of electrons is called electronic device.
These devices are the main building blocks of electronic circuits. Electronics have various branches include, digital electronics, analog electronics, micro electronics, nanoelectronics, optoelectronics, integrated circuit and semiconductor device.
History of electronics Diode vacuum tube was the first electronic component invented by J. Later, Lee De Forest developed the triode, a three element vacuum tube capable of voltage amplification.
Vacuum tubes played a major role in the field of microwave and high power transmission as well as television receivers. InBell laboratories developed the first transistor based on the research of Shockley, Bardeen and Brattain. InJack Kilby of Texas Instruments developed the first integrated circuit.
Integrated circuits contain large number of semiconductor devices such as diodes and transistors in very small area. Advantages of electronics Electronic devices are playing a major role in everyday life. The various electronic devices we use in everyday life include Computers Today, computers are using everywhere.
At home, computers are used for playing games, watching movies, doing research, paying bills and reservation of tickets for railways and airlines.
At school, students use computers to complete their assignments. Mobile phones Mobile phones are used for variety of purposes such as for sending text messages, making voice calls, surfing internet, playing games, and listening songs.
ATM ATM is an electronic telecommunication device particularly used for withdrawing money at any time from anywhere. ATM stands for automated teller machine. The customer can withdraw money up to a certain limit during anytime of the day or night.Common Electrical Devices Used in Physics Words | 8 Pages #7 "Electric Devices and Meters" Physics PHA PT2E Santos, Nickerson Jeff F.

1. The purpose of every circuit is to supply the energy to operate various electrical devices. These devices are constructed to convert the energy of flowing charge into other forms of energy (e.g., light, thermal, sound, mechanical, etc.). Use complete sentences to describe the energy conversions that occur in the following devices.

7Electric Devices And MetersOBJECTIVE:To familiarize the students with the different types of electric devices and meters. There are 3 major aspects while considering the difference between the two inter-related technologies Way of working. The main difference between electrical and electronic circuits is that electrical circuits have no decision making (processing) capability, whilst electronic circuits do.
