Diodes
Diode is a type of Non-linear Component in electrical circuit. A diode is an electronic device having a two-terminal unidirectional power supply i.e. it has two terminals and allows the current to flow only in one direction. Diodes are widely used in modern-day circuits to secure circuits from over-voltage and they are also used to change AC current to DC current.
Diode is a one way valve for electricity. Diodes allow the current to pass through one way if it is forward biased (the anode with the positive terminal and the cathode with the negative one), and it prevents it from passing when it is reverse biased.
- Diodes consist of semiconductor materials, either silicon or germanium.
- It is a two terminal semiconductor device, these two terminals are called the anode and cathode.
- It lets the electricity to flow only in one direction.
- Most diodes have painted line on one end showing the direction or flow. The negative side is normally white
- Current flow through diode only when positive voltage is applied to anode and negative voltage is connected to cathode
- If these voltages are reversed, then the current will not flow.
Applications of Diodes
- They act as shields for solar panels.
- They are used to protect loads from voltage spikes.
- They are used in voltage and converting it from AC to DC.
- They are used to allow an unidirectional flow of current in circuit.
- They differ by its power, and how much current it can handle.
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.
