Web20 de out. de 2024 · For understanding the working of a transistor as switch we use bipolar junction transistor ( BJT) and will construct its current versus voltage curve. There are 3 regions in which transistor operates the first one is active, second one is saturation and third one is cut-off region. WebThe transistor functions as a switch in the cut-off and saturation modes. During the cutoff zone, the transistor is off, and during the saturation period, it is on. Last but not least, a transistor can function as a switch because a little electric current running through one part of it induces a greater current to flow through the other.
