Varactor Diode | Symbol, Characteristics & Applications

Varactor diode is a type of PN junction diode that behaves as a variable capacitor under varying reverse-biased voltage applied to its terminals. It shows this capacitive effect under reverse biased condition only. It has two terminals i.e. anode and cathode. It is also known by other names such as tunning diode or voltage variable … Read more

Difference between Microprocessor and Microcontroller

For beginners in electronics, microprocessors and microcontrollers may seem to be perplexing. Both of them have been designed for real-time applications and they share many common features while at the same time they have significant differences. Both the IC’s – i.e., the microprocessor and microcontroller cannot be distinguished by looking at them, however, if one … Read more

Difference between Database and Data warehouse

Data is at every point of any software application or computer program. It is essential for software developers to be informed about the technologies present at our back-end systems. These systems are responsible for storing, organizing, and processing data for users to promptly find and extract relevant information. They are available with various sizes and … Read more

Stack vs Queue vs Heap

Ever wondered how the data within the database is managed? Or how it is available so easily on our command? This has been possible with the help of data structures. Data can be inserted, updated, arranged, rearranged, deleted, and retrieved efficiently, from the database with the help of data structures. They help organize the storage … Read more

Difference between IPv4 and IPv6

Do you know how a computer distinguishes itself from another in the web of networks? Each computer has its unique IP address which is assigned to every device connected or a part of the network. This unique address behaves as an identifier and is used to identify the device on a network. It is what … Read more

PIN Diode | Symbol, Characteristics & Applications

Pin diode is a diode that has p-type and n-type semiconductor material sandwiching an intrinsic layer. The intrinsic layer is a layer of undoped semiconductor material. This is the structural difference between a normal PN junction diode and a PIN junction diode. Like PN junction diode, ‘P’ refers to the positive p-type region, ‘N’ refers … Read more

Electrical Wiring Color Code

The main reason behind the coloring of electrical wires is to identify the purpose of using them, only by looking at them. It is very important to use the right wire in every connection of electrical wiring. It gives safety, efficient use, and also increment in durability. The commonly used colors in electrical wiring are … Read more

Wind Energy Advantages and Disadvantages

Wind energy is a renewable source of energy and nowadays it is used for the generation of electricity around the world. Wind turbines are utilized for the conversion of wind’s kinetic energy into electrical energy. The Wind blows the blades of the turbine, which is attached to a rotor. The rotor’s rotation causes the generator … Read more
