Web12 de ago. de 2024 · The more base current you drive, the more collector current can flow. One doesn't fight the other. FUrther, you have to keep in mind, the collector current flowing is a result of the EXTERNAL CIRCUIT as well as the BJT itself, so you can't analyze it in isolation. \$\endgroup\$ – A bipolar junction transistor (BJT) is a type of transistor that uses both electrons and electron holes as charge carriers. In contrast, a unipolar transistor, such as a field-effect transistor, uses only one kind of charge carrier. A bipolar transistor allows a small current injected at one of its terminals to control a much larger current flowing between the terminals, making the device capable of amplificat…
