The superconducting material shows some extraordinary properties which make them very important for modern technology. The research is still going on to understand and utilise these extraordinary properties of superconductors in various fields of technology. Such properties of superconductors are listed below- ZeroElectric Resistance(Infinite Conductivity) Meissner Effect: Expulsion ofmagnetic field Critical Temperature/Transition Temperature Critical Magnetic Field Persistent Currents Josephson

Based on the behavior and properties of Superconductors, these are classified into two categories-(1) Type – I Superconductors: Low Temperature Superconductors.(2) Type – II Superconductors: High Temperature Superconductors.td{width:49%}Type – I and Type – II superconductors slightly different in their behavior and properties. The comparison of type-I and type – II superconductors is shown in the table below Type – I Superconductors Type – II Superconductors Low critical temperature

When Superconductors, are cooled below the critical temperature, they expel magnetic field and do not allow the magnetic field to penetrate inside them. This phenomenon in superconductors is called Meissner effect. This phenomenon was discovered by German physicists “Walther Meissner” and “Robert Ochsenfeld” in 1933. During an experiment, they measured the magnetic field outside the superconducting Tin and Lead samples. They observed that when the sample got cooled below the transition (critical

Understanding the short circuit definition and associated risks is crucial for ensuring electrical safety in homes and workplaces. By knowing the common causes of short circuits and employing preventive measures such as regular inspections, proper installation, and protective devices like circuit breakers and GFCIs, we can minimize the dangers associated with short circuits and create a safer environment for everyone.A short circuit phenomenon occurs in electrical circuits and poses potential sa

Voltage drop (VD) occurs whenthe voltage at the end of a run of cable is lower than at the beginning. Any length or size of wires will have some resistance, and running a current through this dc resistancewill cause the voltage to drop. As the length of the cable increases, so does its resistance and reactance increase in proportion. Hence, VD is particularly a problem with long cables runs, for example in larger buildings or on larger properties such as farms. This technique is often used when

When current flows through an electric circuit, the collision between the electrons and atoms of wire causes heat to be generated. How much heat is generated during current flowing through a wire and on what conditions and parameters do the heat generation depend? James Prescott Joule an English physicist, coined a formula which explains this phenomenon accurately. This is known as Joule’s law. What is Joule’s Law of HeatingThe heat which is produced due to the flow of current within an electric

What is Alternating Current?Alternating current is a fundamental aspect of electrical systems that have shaped our world in countless ways. Its ability to be easily generated, converted to different voltages, and transmitted over long distances has made it the preferred choice for power transmission and distribution. Additionally, the many advantages of AC, such as compatibility with various devices and safety features, have made it indispensable in our daily lives.In the world of electricity, t

In this article, we will explore the concept of the mechanical equivalent of heat, which states that mechanical work and heat can be converted into each other. We will also learn about the experiments and discoveries that led to this idea and how it helped to establish the science of thermodynamics.What is the Mechanical Equivalent of Heat?The mechanical equivalent of heat is a term that describes the relationship between mechanical work and heat. It is defined as the amount of work required to

Wiedemann-Franz law is the law which relates the thermal conductivity (κ) and the electrical conductivity (σ) of a material which consists of somewhat freely moving electrons in it. Thermal Conductivity (κ):It is the degree (measure) of capacity of a material to conduct heat. Electrical Conductivity (σ):It is the degree (measure) of capacity of a material to conduct electricity.In metals; when temperature increases, the velocity of free electrons increases and that leads to an increase in heat t

What is Faraday’s LawFaraday’s law of electromagnetic induction (referred to as Faraday’s law) is a basic law of electromagnetism predicting how a magnetic field will interact with an electric circuit to produce an electromotive force (EMF). This phenomenon is known as electromagnetic induction.Faraday’s law states that a current will be induced in a conductor which is exposed to a changing magnetic field. Lenz’s law of electromagnetic induction states that the direction of this induced current
