Correct option is A
Understanding Transistor Saturation Region:
· In a Bipolar Junction Transistor (BJT), the saturation region occurs when both the Base-Emitter Junction (BE junction) and the Base-Collector Junction (BC junction) are forward biased.
· This happens when the transistor is fully ON, allowing maximum current flow from collector to emitter.
Voltage Conditions in Saturation Region (NPN Transistor):
·
Base-Emitter Voltage (VBE):
· The base-emitter junction is forward biased.
· For an NPN transistor, VBE is positive and typically around 0.7V (for silicon transistors).
·
Collector-Base Voltage (VCB):
· The base-collector junction is also forward biased in the saturation region.
· Since the collector is at a lower potential than the base in saturation, VCB is negative.
