For a transistor to act as a switch, it must be operated in

Options

  1. AActive region
  2. BSaturation and cut-off region
  3. CCutoff region only
  4. DSaturated region only

Correct answer

B. Saturation and cut-off region

Step-by-step solution

The saturation zone and cut-off area are known as the transistor switch’s working regions. This implies that, by switching between its “top-off” (saturation) and “absolute OFF,” the transistor is used as a switch.
