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

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

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

The superposition theorem is a fundamental principle in electrical engineering that states that the response of a linear system to any input can be represented as the sum of the responses to individual inputs. In other words, the output of a linear system to a combination of inputs is equal to the sum of the outputs that would be produced by each input individually.The superposition theorem states that:“In any linear bilateral network with multiple sources, the response (voltage and current) in

Thevenin’s Theorem is a principle in electrical engineering that allows the complex impedance of an electric circuit to be reduced to a single equivalent impedance. It states that any linear, two-terminal electrical network can be represented by an equivalent circuit consisting of a single voltage source in series with a single impedance. The voltage of the source is the open-circuit voltage of the network, and the impedance is the impedance seen looking into the circuit with the voltage source

Norton’s Theorem is a principle in electrical engineering that allows the complex impedance of an electric circuit to be reduced to a single equivalent impedance. It states that any linear, two-terminal electrical network can be represented by an equivalent circuit consisting of a single current source in parallel with a single impedance.

Millman’s Theorem is a principle in electrical engineering that allows the complex impedance of a series of resistors and voltage sources to be reduced to a single equivalent impedance.

The resistor is the equivalent resistance of the circuit, and the voltage of the source is the equivalent

The Reciprocity Theorem is a principle in electromagnetics that relates the voltage and current at two points in a linear, passive network.

The Compensation Theorem is a principle in electrical engineering that allows the response of a linear, two-port network to be determined based on the response of the network to a single input. It states that the response of a two-port network to any two inputs can be determined by measuring the response of the network to a single input and a zero input.The Compensation Theorem is based on the idea that the response of a linear, two-port network to any two inputs can be represented by a matrix,
