WebBipolar Junction Transistor Concepts Forward Active NPN BJT Operation VC > VB > VE Fundamentals • A BJT is often considered to be a current amplifier because a small current entering the base will typically result in a large current into the collector. Or we can say that: IC = β IB, where β is a large number, typically greater than 100. WebThe BJT is not in active mode. In the previous example, the collector resistor was 1K , whereas in this example the collector resistor is 10K. Thus, there is 10X the voltage drop across the collector resistor, which lowers the collector voltage so much that the BJT cannot remain in the active mode. bipolar 2 vs anxiety and depression
