Question 1

What is the function of a transistor in the cut-off state?

  • Allows current flow
  • Prevents current flow
  • Amplifies signal

💡 Hint: Remember, cut-off means it's OFF.

Question 2

In the saturation state, how does the transistor behave?

  • True
  • False

💡 Hint: Compare to an electronic circuit.
