Which of the following is true for the saturation region of BJT transi...
The correct answer is option 'B': The collector current is proportional to the square root of the collector current.
Explanation:
The saturation region is one of the operating regions of a bipolar junction transistor (BJT). In this region, both the base-emitter junction and the base-collector junction are forward-biased. The saturation region occurs when the base-emitter junction is forward-biased and the base-collector junction is also forward-biased with a relatively small base current.
In the saturation region, the transistor is in full conduction mode, and the collector current is at its maximum value. The behavior of the collector current in this region can be described by the following equation:
Ic = β * Ib
where Ic is the collector current, Ib is the base current, and β is the current gain or the beta value of the transistor.
However, in the saturation region, the collector current is not directly proportional to the base current. Instead, it is proportional to the square root of the base current.
The relationship between the collector current and the base current in the saturation region is given by:
Ic = (β * Ib)^(1/2)
This equation shows that the collector current increases with the square root of the base current. As the base current increases, the collector current also increases, but at a decreasing rate due to the square root relationship.
Therefore, option 'B' is the correct answer: The collector current is proportional to the square root of the collector current.
Note: It's worth mentioning that the equation mentioned here assumes that the transistor is in the active region and not in the cutoff or saturation regions. The behavior of a transistor in different regions can be described by different equations.
