the nature of electronics as a branch of physics
Electronics Today, most electronic devices use semiconductor components to perform electron control. The study of semiconductor devices and related technology is considered a branch of solid-state physics, whereas the design and construction of electronic circuits to solve practical problems come under electronics engineering. This article focuses on engineering aspects of electronics.
Ampere The ampere (/ˈæmpɪər, æmˈpɪər/;[1] symbol: A),[2] often shortened to "amp",[3] is the base unit of electric current in the International System of Units (SI).[4][5] It is named after André-Marie Ampère (1775–1836), French mathematician and physicist, considered the father of electrodynamics.
