In this mode the transistor acts as a closed switch.ģ. The collector current becomes independent of base current. The negative terminal of the battery is connected to the emitter. ![]() In which region a transistor acts as a closed switch?Ĭlarification: In this mode, both the junctions are forward biaseC. In this mode the transistor acts as an open switch.Ģ. There is negligibility current due to minority carriers. The transistor has practically zero current because the emitter does not emit charge carriers to the base. ![]() In which region a transistor acts as an open switch?Ĭlarification: In this mode, both the junctions are reverse biaseC.
