Emitter, Base, Collector.<\/p>\n<p>A BJT (bipolar junction transistor) is a three-terminal semiconductor device used to amplify and switch electronic signals and electrical power. It is composed of three semiconductor regions: the emitter, base, and collector. The emitter and collector regions are heavily doped with impurities, while the base region is lightly doped. The emitter and collector regions are connected by a thin layer of base material.<\/p>\n<p>When a small voltage is applied to the base-emitter junction, a large current can flow through the collector-emitter junction. This is because the base region is so thin that a small change in the base-emitter voltage can cause a large change in the collector-emitter current.<\/p>\n<p>BJTs are <div class=\"telegram-channel-container\">\r\n        <a href=\"https:\/\/t.me\/pscnotes2025\" target=\"_blank\" class=\"telegram-channel-button\">\r\n            <span class=\"telegram-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 496 512\">\r\n                    <path fill=\"white\" d=\"M248,8C111,8,0,119,0,256s111,248,248,248s248-111,248-248S385,8,248,8z M362,177L320,367c-3,14-10,18-20,14l-56-41l-27,26 c-3,3-5,5-10,5l4-63L323,196c5-5-1-7-8-3l-98,62l-42-13c-9-3-10-9,2-14l162-63C351,160,365,164,362,177z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Join Our Telegram Channel\r\n        <\/a>\r\n    <\/div> used in a wide variety of electronic devices, including amplifiers, oscillators, and switches.
