The transfer characteristic of n-p-n transistor in CE configuration is shown in the figure.

  1. Identify the cut *** region, active region, saturation region from the figure.

  2. In which of these regions, a transistor is said to be switched ***.

  3. For a CE transistor amplifier, the audio signal voltage across collector resistance of 2.0 kΩ is 2.0 V. Suppose the current amplification factor of the transistor is 100. What should be the value of RB in series with VBB supply of 2.0 V, if DC base current has to be 10 times the signal current?

  4. In the working of a transistor, the emitter base (EB) junction is forward biased while collector base (CB) junction is reverse biased. Why?
