Question

Quizplus · Accepted Answer

Transistors are typically used in the active, or linear, region when they are used to amplify weak signals. This allows for a proportional amplification of the signal without distortion, making them useful in a wide range of applications such as audio amplifiers, RF circuits, and more. While transistors can also be used as switching circuits, this typically involves operating them in the saturation or cutoff regions, which are not the active region. Rectification involves the use of diodes, not transistors. The breakdown region is not an operating region for transistors, but rather a failure mode that should be avoided.
