What exactly is Biot Savart Law?The Biot Savart Law is a mathematical equation that describes the magnetic field produced by a constant electric current. It connects the magnetic field to the electric current’s size, direction, length, and proximity. Ampere’s circuital law and Gauss’ theoremare both consistent with the Biot-Savart law.The Biot-Savart law is essential to magnetostatics, having a similar function toCoulomb’s lawin electrostatics.Biot Savart Law Statement:According to the Biot-Sava

Ampere’s circuital law is a fundamental law in electromagnetism that relates the magnetic field around a conductor to the electric current flowing through the conductor. It is named after French scientist André-Marie Ampère, who developed the law in the early 19th century.Ampere’s circuital law Equation:Ampere’s circuital law can be expressed mathematically as:∮B⋅ds =µ0Iencwhere:∮B⋅ds – The integral of the magnetic field (B) around a closed path (ds)µ0 – The permeability of free space, a constan

In physics, Gauss’s Law is a fundamental relationship that connects the distribution of electric charge to the resulting electric field. It is a generalization of Coulomb’s Law, which describes the electric force between two-point charges. Gauss’s Law states that the flux of the electric field through any closed surface is equal to the charge enclosed within that surface.Gauss’s law Mathematical Expression:Mathematically, Gauss’s Law can be expressed as:∫E⋅dA = q/εwhere:E – The electric fielddA

Curie’s Law is a relationship in physics that describes the behavior of magnetic materials at different temperatures. It states that the magnetic moment per unit volume of a material is directly proportional to the temperature. The magnetic moment of a material is a measure of the strength of its magnetization.Curie’s Law Expression:Mathematically, Curie’s Law can be expressed as:M/V = C/Twhere:M – The magnetic moment per unit volumeV – The volume of the materialC – A constant of proportionality

There are some materials mainly metals, such as silver, copper, aluminum, which have plenty of free electrons. Hence this type of materials can conduct current easily that means they are least resistive. But the resistivity of these materials is highly dependable upon their temperature. Generally metals offer more electrical resistance if temperature is increased. On the other hand the resistance offered by a non-metallic substance normally decreases with increase of temperature.If we take a pie

Hopkinson’s Law is a relationship in materials science that describes the behavior of materials under high strain rates. It states that the stress of a material is proportional to the strain rate at which it is deformed. Hopkinson’s Law is named after Sir Benjamin Baker Hopkinson, who first proposed it in the early 20th century.Hopkinson’s Law Mathematical Expression:Mathematically, Hopkinson’s Law can be expressed as:σ = k ε̇where:σ – The stress of the materialk – The material’s strength coeffi

What is Reactance?Reactance (also known as electrical reactance) is defined as the opposition to the flow of current from a circuit element due to its inductance and capacitance. Greater reactance leads to smaller currents for the same applied voltage. Reactance is similar to electric resistance, although it differs in several respects.When an alternating current passes through the electric circuit or element, the phase, and amplitude of current will change. The reactance is used to compute this

The Wiedemann–Franz law is a relationship in physics that relates the electrical conductivity of a metal to its thermal conductivity. It states that the ratio of the electrical conductivity to the thermal conductivity of a metal is proportional to the temperature and is equal to a constant known as the Lorenz number. The Wiedemann–Franz law is named after German physicists Georg Wiedemann and Robert Franz, who first proposed it in the mid-19th century.Wiedemann–Franz law Derivation:Mathematicall

What is Equivalent Resistance?The equivalent resistance is defined as a point where the total resistance is measured in a parallel or series circuit (in either the whole circuit or in a part of the circuit). The equivalent resistance is defined between two terminals or nodes of the network. Equivalent resistance may sound complicated, but it’s just a technical way to say “total resistance”.In the equivalent resistance of a network, a single resistor could substitute the complete network so that

What is Electrical Resistance?Resistance (also known as ohmic resistance or electrical resistance) is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω).The larger resistance, the greater the barrier against the flow of current.When the potential difference is applied to a conductor, the current starts flowing, or the free electrons start moving. While moving, the free electrons collide with the atoms and
