- Transistor: A transistor has two PN junctions i.e., it is like two diodes. The junction between base and emitter may be called emitter diode. The junction between base and collector may be called collector diode.
- The transistor can act in one of the three states:
- CUT-OFF: EMITTER DIODE AND COLLECTOR DIODE ARE OFF.
- ACTIVE: EMITTER DIODE IS ON AND COLLECTOR DIODE IS OFF.
- SATURATED: EMITTER DIODE AND COLLECTOR DIODE ARE ON.
Note: Please understand that the question is asking about the regions of a biased transistor. Biasing is a set of DC voltages that we apply at the Base-emitter 'or' emitter-collector terminal. There are three possibilities based on this voltage, i.e. Active Region, Cut-off region, and Saturation region.
