The controlled flow of electrons has been used through various techniques and forms what’s known as electronics.
Importance of electronics in our daily life
Besides the common electronic gadgets such as radio and TV receivers, audio and videotape recorders, frequency synthesisers, calculators, cameras, musical doorbells, etc., electronics have offered it is services in different walks of life. The computer, which has revolutionized the world, is one of the major achievements of electronics. In medical diagnostics and surgery, all scanning devices and techniques use electronics in some form or the other.
The term ‘electronics’ has been coined from electron-the key particle, the flow of which through a conductor gives us electric current or simply current. This current can be produced with batteries and generators-machines, which generate electric power, either DC or AC, at 50 Hz. This current can be used for various purposes such as illumination, heating, and driving the motors. However, electronics has far-reaching capabilities and potentialities.
- The flow of electrons has been regulated and controlled in electronic devices under the stimuli of external influences, which may be called signal, message, data or any other name appropriate for the occasion.
- The controlled flow of electrons has been used through various techniques and forms what’s known as electronics.
- It is tough to find anything starting from household goods, transports, health, communication, entertainment, multimedia, and the Internet, where electronics haven’t made it.
