Questions & Step-by-Step Solutions

What is the main characteristic of a BJT in the active region?
  • Step 1: Understand what a BJT is. A BJT (Bipolar Junction Transistor) is a type of transistor used to control current.
  • Step 2: Learn about the active region. The active region is one of the three operating regions of a BJT.
  • Step 3: Know the function of the active region. In this region, the BJT can control and amplify current.
  • Step 4: Recognize the importance of amplification. This ability to amplify current makes BJTs useful in devices like amplifiers.
