Electronics started in the early 1900s when Lee Deforest invented the triode to amplify weak radio signals. Until the 1950s this field was actually called “radio technology” because its primary application was in transmitters, receivers and vacuum tubes, all key elements of radios. today most electronic devices use semiconductor components to perform their functions. The design and construction of electronic circuits is a part of the field of electrical engineering.
About the author
I began college studying electrical engineering. My sophomore year I took my first electronics course. Although I passed the course (with the help of a very smart lab partner), I decided that electricity was “magic” and electrical engineering was not for me. I switched to mechanical engineering, got my degree and stared a career in manufacturing. Ironically, I ended up working in plants that built transformers, regulators, breakers and generators. I could not escape the world of electricity and electronics .
