Questions & Step-by-Step Solutions

What type of transistor is a BJT?
  • Step 1: Understand what a transistor is. A transistor is a device that can control electrical current.
  • Step 2: Learn about the types of transistors. There are two main types: bipolar and unipolar.
  • Step 3: Focus on the BJT, which stands for Bipolar Junction Transistor.
  • Step 4: Know that 'bipolar' means it uses two types of charge carriers: electrons and holes.
  • Step 5: Remember that electrons are negatively charged, and holes are positively charged.
  • Step 6: Conclude that a BJT is a bipolar device because it uses both types of charge carriers to function.
