Most commonly used transistors have Vce less than 0.4 V for the active region.
Which of the following is true for the active region of an npn transistor?
The base current and the collector current are directly proportional to each other and the potential difference between the collector and the base is always less than 0.4 V.
Which of the following is true for the saturation region of BJT transistor?
The collector current is directly proportional to the base current in the saturation region of the BJT.
Which of the following is true for a npn transistor in the saturation region?
The commonly used npn transistors have a potential difference of around 0.5V between he collector and the base.
