V-I Characteristics of Transistors
The behavior of a transistor is observed with the help of its V-I characteristics
There are two types of characteristic.
- Input Characteristic
- Output Characteristic
Input Characteristic
Input characteristic of a transistor gives the relationship between input current and input voltage for a constant output voltage.
- The input characteristic is a curve plotted between IE and VEB. At constant base voltage VCB.
- Keeping VCB constant(e.g.2V) note down IEB for different VEB.
- This will give input characteristic.
Output Characteristic
Output characteristics of a transistor gives the relationship between output current and output voltage for constant input current.
- It is the curve between Ic and VCB at constant emitter current.
- Keeping emitter current le fixed note the collector current Ic for various values of collector base voltage VCB.
The output characteristics has 3 basic regions:
- Active region – defined by the biasing arrangements
- Cutoff region – region where the collector current is OA
- Saturation region- region of characteristics to the left Of VCB = 0V
Non-linear Components
In electrical circuits, Non-linear Components are electronic devices that need an external power source to operate actively. Non-Linear Components are those that are changed with respect to the voltage and current. Elements that do not follow ohm’s law are called Non-linear Components. Non-linear Components do not follow superposition principle and homogeneity .They mainly manipulate, amplify, switch or control the flow of electric current or voltage in a circuit. Non-linear Components – like diodes , transistors, integrated circuits (ICs), and sensors require power to do their job.
A circuit is an interconnection of components. These components are capable of performing active functions like amplification, rectification and switching they are called as Non-linear Components. In this article, we will learn about the role of Non-linear Components – in Electrical Circuits, their properties, types, working, advantages, disadvantages, and applications of Non-linear Components.
