Extracted text: 2 a) i) Draw typical output characteristics of a common emitter npn transistor and clearly identify the active, saturation, and cut off regions on your drawing. ii) Explain how you can find the common emitter de current gain, B, and the common emitter ac current gain, hre, from the common emitter output characteristics of an npn transistor. You need to draw typical output characteristics in scales and provide numerical calculations to support your explanation.
