Question

Draw a circuit diagram for studying the input and output characteristics of a n-p-n transistor in common emitter configuration. Using the circuit, explain how input, output characteristics are obtained

Solution

Using the circuit, input characteristics are represented by a graph showing variation between the base current and the base-emitter voltage. This characteristic or graph is further used to evaluate input dynamic resistance of the transistor as the slope of the graph. Similarly, the same circuit is used to find the output characteristics of the circuit using the graph representing the variation of the collector current and the emitter voltage, keeping base current fixed. Here, the output dynamic resistance is evaluated as the slope of the output characteristics graph.
