V-I Characteristics of Diode
The V-I characteristics of the diode can easily be understood under the following headings.
- Forward-Biased Diode
- Reverse-Biased Diode
Forward-Biased Diode
- In forward biasing semiconductor is connected to an external source when the p-type semiconductor is connected to the positive terminal of the source or battery and the negative terminal to the n-type, then this type of junction is said to be forward-biased. In forward bias, the direction of the built-in electric field near the junction and the applied electric field are opposite in direction. This means that the resultant electric field has a magnitude lesser than the built-in electric field due to this there is less resistivity and therefore depletion region is thinner. In silicon, at the voltage of 0.6 V, the resistance of the depletion region becomes completely negligible.
Reverse-Biased Diode
- In reverse biasing, the n-type is connected to the positive terminal and the p-type is connected to the negative terminal of the battery. In this case, the applied electric field and the built-in electric field are in the same direction and the resultant electric field has a higher magnitude than the built-in electric field creating a more resistive, therefore depletion region is thicker. if the applied voltage becomes larger, then the depletion region becomes more resistive and thicker.
The V-I characteristic of a diode in forward and reverse-biased conditions are,
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.
