What is a superconductor? 

We want to know how superconductors work and what a superconductor material is. The material that achieves the superconductivity property is known as a superconductor. Now, the question is, what is the superconductivity property? How can a material achieve the superconductivity property?

This phenomenon was first discovered in 1911 by Heike Kamerlingh Onnes, and it has since led to various technological advancements and applications.

Capacitance and Capacitor Must Know Electrical Engineer

Capacitance and Capacitor


A capacitor is an electronic component designed to store and release electrical energy in a circuit. It consists of two conductive plates separated by an insulating material, known as the dielectric. The primary property associated with capacitors is capacitance, which is a measure of the ability of the capacitor to store charge. Capacitance is typically denoted by the symbol "C" and is measured in farads (F).

How Social Engineering Attacks Impact Brand Reputation?

Whether it’s managing daily operations, communicating with teams, or even serving customers, your entire business depends on technology. However, here’s one concerning thing that, as a decision-maker, you should look into. No matter how advanced or modern your IT systems are, the real vulnerability often lies with people. 


Cybercriminals are aware of this fact. So, instead of targeting firewalls or software, they target human behavior. And this is known as a social engineering attack. It’s related to clever manipulations. These attacks can take many forms, such as phishing emails that look genuine, phone calls from trusted sources, or even someone walking into an office pretending to deliver a package.

Magnetic Hysteresis

Magnetic Hysteresis


What is Magnetic Hysteresis?

Magnetic hysteresis is a phenomenon observed in ferromagnetic materials, which are materials that can be easily magnetized. When a ferromagnetic material is subjected to a changing magnetic field, such as the alternating current in a transformer or the changing magnetic field in a magnetic circuit, the magnetic properties of the material exhibit a lag or delay in response.

Electromagnetic Induction

Electromagnetic induction is a phenomenon in physics where a changing magnetic field induces an electromotive force (EMF) or voltage in a conductor. This principle was first discovered by Michael Faraday in 1831 and later formulated by him and Joseph Henry.

The key points of electromagnetic induction include:

Faraday's Law of Electromagnetic Induction:

Magnetism and Electromagnetism

Permeability is a fundamental property that characterizes a medium's ability to allow the flow of a substance, typically fluid, through it. Two essential types of permeabilities—absolute and relative—play crucial roles in understanding and analyzing the transport of fluids in different materials. 

Absolute permeability refers to the intrinsic ability of a medium to transmit fluid under a specific set of conditions, often measured in units such as darcies. It is an inherent property that depends on the medium's internal structure, porosity, and connectivity between its pores or fractures.

Electrostatics and Most Related Theory

Electrostatics is a branch of physics that explores the study of stationary electric charges and their interactions. It deals with the behavior of electric charges at rest, investigating phenomena such as electric fields, potential differences, and the forces that arise between charged objects. At the heart of electrostatics is Coulomb's Law, which quantifies the force between two point charges and highlights the inverse square relationship between the distance separating them. 

The fundamental concept of electric charge, whether positive or negative, forms the basis for understanding the intricate workings of electrostatic phenomena.

DC Network Theorems

 Kirchhoff’s Laws: Kirchoff's Law means Kirchoff's current law and Kirchoff's voltage law, measuring the total current and total voltage accordingly.

Kirchhoff's Current Law (KCL): 
The total current entering a junction is equal to the total current leaving the junction.
Kirchhoff's Voltage Law (KVL): 
The total voltage around any closed loop in a circuit is equal to the sum of the voltage drops.


Determination of Voltage Sign: 

Electric Current and Ohm’s Law

Electric current and Ohm's law is very much essential parts of knowing as an electrical engineer.  I'll provide brief explanations for each term:


Electron Drift Velocity:
The average velocity of electrons in a conductor in response to an electric field.

Charge Velocity and Velocity of Field Propagation:

Charge velocity refers to the movement of electric charge, typically electrons. The velocity of field propagation is the speed at which changes in the electric field travel through a medium.

Renew Electrical Work, Power and Energy

Electrical work, power, and energy are fundamental concepts within the realm of electrical engineering and physics, playing a crucial role in our modern technological society. Electrical work refers to the transfer of energy through the flow of electric charge, typically achieved by moving electrons through a conductor. This flow of charge is harnessed to perform various tasks, from powering household appliances to driving complex industrial machinery.


Power, in the context of electricity, is the rate at which work is done or energy is transferred. It is measured in watts and determines how quickly electrical energy is converted into other forms, such as mechanical, thermal, or light energy. Understanding power is essential in designing efficient electrical systems and ensuring they meet the demands of different applications.

What is the operating ambient temperature of a fuse?


💗

Operating ambient temperature of a fuse

Ambient temperature is the air temperature of any object or environment where equipment is stored. In a computing context, maintaining an appropriate ambient temperature is crucial to the proper functioning and longevity of any equipment. 

Ambient temperature is a fancy way of saying the “outside air” surrounding the fuse.

Normally, the fuses are tested in "laboratory conditions" by the safety agencies such as

UL and CSA. The lab conditions are almost always set at 25°C or 77°F. Unfortunately, real-world conditions are not those found in a laboratory.

Fuseheat-sensitives devices meaning that it takes heat (via the overcurrent) in order to melt the fuse element inside the fuse. The more heat...the faster it takes to melt the fuse element...the less heat...the longer it takes to melt the fuse element.

If a fuse will be subjected to a higher temperature than 25°C, then the fuse amperage will need to be increased as to compensate for the higher temperature (to avoid "nuisance tripping"). Likewise, if the fuse will be used at a lower temperature, then the fuse amperage needs to be lowered (or else it might never open).

The rule of thumb is that for every 20°C higher or lower in temperature, the fuse should be re-rated by higher or lower 10-15%.

An example of a fuse re-rating when higher ambient temperatures are present:
Normal full-load current: 1 Amp

Normal fuse sizing: 1.5 Amps (135% of full load current taken to the next higher standard rating)
Ambient Temperature: 65°Clow-temperature

Re-rating: Re-rating: 2 Amps (130% of normal fuse rating)

Conversely, when a fuse is intended to be used in extremely low temperature conditions, the fuse must have a lower rating than that in normal conditions.

An example of the fuse re-rating when lower ambient temperatures are present:
Normal full-load current: 1 Amp

Normal fuse sizing: 1.5 Amps (135% of full load current taken to the next higher standard rating)
Ambient Temperature: -15°C

Re-rating: 1.2 Amps (70% of normal fuse rating taken to the next higher standard fuse rating)




Ambient temperature and operating temperature

What is the difference between Ambient temperature and operating temperature, let's know-

Ambient temperature is the temperature of the air around the equipment. This range is typically between 60°F and 75°F (15°C and 24°C ). 

The operating temperature is the temperature of the equipment itself. Since the equipment is (typically) generating heat, the operating temperature will be higher than the ambient temperature.
