"The bipolar junction transistor (BJT) is a three-terminal semiconductor device. For an NPN type, the base-emitter junction is forward-biased, while the base-collector junction is reverse-biased. The collector current (Ic) is equal to the base current (Ib) multiplied by the beta (β) of the device."
The term "electronics" is often used interchangeably with "electricity," yet the distinction is profound. While electricity deals with the generation and distribution of power (voltage and current), electronics is the study of the controlled flow of electrons to process information or perform specific tasks. It is the science of electron behavior in vacuum, gases, and semiconductors. electronics demystified pdf
