Question

Draw the circuit diagram of the ‘set-up’ used to study the characteristics of a npn transistor in its common emitter configuration. Sketch the typical (i) Input characteristics and (ii) Output characteristics for this transistor configuration

To study the characteristics of an NPN transistor in its common emitter configuration, we first need to understand how to set up the circuit diagram. This configuration is widely used in amplifiers and switching applications. Let’s break down the circuit setup and then look at the input and output characteristics.

Circuit Diagram of NPN Transistor in Common Emitter Configuration

The common emitter configuration involves connecting the emitter terminal of the NPN transistor to the ground. Here’s a simple representation of the circuit:

Transistor: NPN transistor (Q1)
Power Supply: Vcc connected to the collector through a resistor (Rc)
Input Signal: A resistor (Rb) connected to the base, where the input signal (Vin) is applied
Emitter Resistor: A resistor (Re) connected from the emitter to ground

The circuit can be visualized as follows:
