The Correct Statement for the Biasing of an NPN Transistor as an Amplifier
To determine the correct statement about the biasing of an NPN transistor as an amplifier, let's analyze each option:
a) The holes go from the base region to the emitter region:
This statement is correct. In an NPN transistor, the base region is p-type, which means it has an excess of holes. When the transistor is biased, a small current flows from the base to the emitter, carried by holes.
b) The electrons go from the collector region to the base region:
This statement is correct. The collector region in an NPN transistor is n-type, which means it has an excess of electrons. When the transistor is biased, a larger current flows from the collector to the base, carried by electrons.
c) The electrons go from the emitter region to the base region and then to the collector region:
This statement is correct. When the NPN transistor is biased, the emitter is heavily doped and acts as the source of electrons. These electrons flow into the base region, where a small fraction recombines with holes, while the majority continues to the collector region. Therefore, the electrons do go from the emitter to the base and then to the collector.
d) The electrons go from the base region to the collector region:
This statement is not correct. In an NPN transistor, the majority of the current flows from the collector to the base, and only a small fraction flows from the base to the emitter. Electrons do not flow directly from the base to the collector.
In summary, the correct statement for the biasing of an NPN transistor as an amplifier is:
- The holes go from the base region to the emitter region.
- The electrons go from the collector region to the base region.
- The electrons go from the emitter region to the base region and then to the collector region.
Therefore, option d) is not correct.
