In Forward Active region Base-emitter junction is forward biased (VBE>0) and Collector-Base junction is reverse biased (VCB>0). In this case, the forward bias of the BE junction will cause the ... WebMay 22, 2024 · If properly designed, this current will be sufficient to put the BJT into saturation. The BJT acts as a switch, completing the circuit between the DC supply, the LED and the current limiting resistor, \(R_C\). For this to work reliably, we have to make sure that the ratio of saturation current to base current is much less than \(\beta\).

WebForward bias Is applied to emitter base junction and reverse bias is applied to collector base junction. The forward bias in the emitter-base junction causes electrons to move toward base. This constitute emitter current, IE. As this electrons flow toward p-type base, they try to recombine with holes.
