WebNov 23, 2024 · October 25, 2024 by Electrical4U. Bipolar Junction Transistor is a three terminal device. Whatever may be the use of a transistor either as an amplifier or as a switch it must have one input circuit and one output circuit. To facilitate the input and output circuit a transistor should have four terminals – two for input and two for output ... WebIn cutoff mode, the brake is engaged (zero base current), preventing motion (collector current). Active mode - is the automobile cruising at a constant, controlled speed (constant, controlled collector current) as dictated by the driver. Saturation - the automobile driving up a steep hill that prevents it from going as fast as the driver wishes. crystonation
