Computer History Archives Project (CHAP) | 1962 "TRANSISTORS" - How NPN Transistors Function, training film; electronics; circuits (HD) @ComputerHistoryArchivesProject | Uploaded September 2021 | Updated October 2024, 1 week ago.
TRANSISTORS: An vintage 1962 training film details the functions of the NPN transistor. Clear diagrams and narration covers key concepts of electron flow in NPN transistor circuits. NPN transistors are a type of bipolar transistor with three layers that are used for signal amplification.
"NPN" denotes a “negative-positive-negative” transistor, which is controlled by a current flow.
The NPN transistor is divided into three sections: emitter, base, and collector. This is Part 3 of the Army series of electronics training on Transistors, but it stands on its own as an educational tool. Exceptionally good quality; 20 mins, produced by U.S. Army. Uploaded by the Computer History Archives Project (CHAP) for historical and educational content.

{The first transistorized computer in the U.S. was the TRADIC (for TRAnsistor DIgital Computer or Transistorized Airborne Digital Computer) completed in 1954. It was built by J.H.Felker of Bell Labs for the United States Air Force.}
