Question

when does a transistor act as a switch????​

Answer 1

Answer:

Based on the voltage applied at the base terminal of a transistor switching operation is performed. When a sufficient voltage (Vin > 0.7 V) is applied between the base and emitter, collector to emitter voltage is approximately equal to 0. Therefore, the transistor acts as a short circuit

Answer 2

Answer:

hi friend,

here is your answer

Transistor as a switch

If both the junctions are Open Circuits in reference to the conditions mentioned above then Transistor will not conduct and acts as OFF SWITCH.

If both the junctions are Short Circuits in reference to the conditions mentioned above then Transistor will not conduct and acts as ON SWITCH.
