Draw the typical

The input and output characteristics of n-p-n transistor in CE configuration is given below:

Input resistance is defined as the ratio of change in base-emitter voltage (ΔV_BE) to the change in base current (ΔI_B) at a constant collector-emitter voltage.

Current amplification factor (β) is defined as the ratio of the change in the collector current to the change in the base current at a constant collector-emitter voltage when the transistor is in active state.
