Emitter Or Input Characteristics

In case of common emitter p-n-p transistor input characteristic is a graph drawn.

In a transistor output characteristics commonly used in common emitter configuration, the base current I_(B) , the collector current I_(C) and the collector-emitter voltage V_(CE) have values of the following orders of magnitude in the active region

Draw a circuit diagram of a transistor amplifier in CE configuration. Define the terms (i) Input resistance and (ii) Current amplification factor. How are these determined using input and output characteristics?

The input characteristics of a transistor in CE mode is the graph obtained by plotting
