To solve the question regarding the characteristics of a transistor in common emitter mode, we will draw and label three types of curves: the input characteristic curve, the output characteristic curve, and the transfer characteristic curve. ### Step-by-Step Solution: 1. **Input Characteristic Curve:** - **Axes:** The x-axis represents the input voltage (V_BE) in volts, and the y-axis represents the input current (I_B) in microamperes (µA). - **Curve Description:** The curve starts from the origin and rises gradually. Initially, there is a small increase in input current with an increase in input voltage until it reaches a certain threshold (approximately 0.6V for silicon transistors). Beyond this point, the current increases more rapidly as the transistor enters the forward active region. - **Labeling:** Mark the breakdown cutoff voltage (around 0.6V) on the x-axis. Label the curve as "Input Characteristic Curve." ...
