Answer #1

To operate a transistor it must be polarized, that is to say it applies different voltages on its pins E, B, C.

The transistor is blocked when its two junctions are in reverse bias .

The transistor is in direct normal operation when the control junction BE is in direct polarization and the junction BC is in reverse bias

The transistor is in reverse normal operation when the control junction BE is in reverse bias and the junction BC is in forward bias

The transistor is saturated when its two junctions are in direct polarization.
