WebJan 31, 2013 · So increasing the bias voltage by 0.4 volts GREATLY amplified the current flow through the resistor, far more than increasing the transistor's emitter-collector voltage by 0.4 volts. If the base voltage (bias voltage) is too low, practically no current can flow through the transistor and it effectively operates as a switch that is opened. WebA type of field-effect transistor called a unipolar transistor only employs one kind of charge carrier. A bipolar transistor can be used for switching or amplification by allowing a tiny current to be injected at one of its terminals and controlling a much greater current flowing between two other terminals.
