Mecatronica
eletronics is the branch of science and technology which makes use of the controlled motion of electrons through different media and vacuum. the ability to control electron flow is usually applied to information handling ordevice control. electronics is distinct from electrical power. this distinction started around 1906 with the inventron by LEE DE FOREST of the triode, which made electrical amplification possible with a non mechamical device. until 1950 this field was called "radio technology" because its principal application was the design and theory of radio transmitters, receivers and vacuum tuber.
Most eltronic devices today use semiconductor components to perform eltron control. the study of semiconductor devices and related tecnology is considered a branch os phisics, eletronic circuits to solve pratical problems come under eletronics enginering. this article focuses an engineering aspects of
