The collector of the transistor should be of?

Solution

  1. Transistor: It is a type of semiconductor device that is used for both conducting and insulating the electric current or voltage.
  2. A transistor generally acts as a switch or an amplifier.
  3. Parts of a transistor:
    - Base: This is used to activate the transistor. It is lightly doped and less in size.
    - Collector: The collector's purpose in a transistor is to collect the majority of charge carriers from the emitter.
    - Emitter: It can be defined as the negative lead of the transistor. It is highly doped and larger than the base.
  4. The collector of a transistor is moderately doped.
  5. It is the portion where the charges are accumulated, and thus heat is released.
  6. So, to protect the transistor from heating up and burning, the collector is always larger in size than that of the emitter & base region.

Thus, the collector of the transistor should be of large size and moderate doping.
