Ohm's Law

StarStarStarStar

Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points, expressed as I=VRI = \frac{V}{R}.

StarStarStarStar

Faraday's Law of Electromagnetic Induction

StarStarStarStar

Faraday's Law states that the induced electromotive force in any closed circuit is equal to the negative of the time rate of change of the magnetic flux enclosed by the circuit: E=dΦBdt\mathcal{E} = -\frac{d\Phi_B}{dt}.

StarStarStarStar

Lorentz Force

StarStarStarStar

The Lorentz force is the force exerted on a charged particle moving through an electric and magnetic field: F=q(E+v×B)\vec{F} = q(\vec{E} + \vec{v} \times \vec{B}).

StarStarStarStar

Series and Parallel Circuits

StarStarStarStar

In series circuits, components are connected end-to-end, while in parallel circuits, they are connected alongside each other, affecting resistance and current flow.

StarStarStarStar

Inductance

StarStarStarStar

In inductance, a change in current in one coil will induce a voltage in a neighboring coil, defined as L=NΦBIL = \frac{N \Phi_B}{I}.

StarStarStarStar

Magnetic Field

StarStarStarStar

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, materials, and currents.

StarStarStarStar

Magnetic Flux

StarStarStarStar

Magnetic flux is a measure of the amount of magnetic field passing through a given area, defined as ΦB=BdA\Phi_B = \int \vec{B} \cdot d\vec{A}.

StarStarStarStar

Maxwell's Equations

StarStarStarStar

Maxwell's Equations are a set of four equations that form the foundation of classical electrodynamics, classical optics, and electric circuits.

StarStarStarStar

Kirchhoff's Current Law

StarStarStarStar

Kirchhoff's Current Law states that the total current entering a junction must equal the total current leaving the junction.

StarStarStarStar

Kirchhoff's Voltage Law

StarStarStarStar

Kirchhoff's Voltage Law states that the sum of all voltages around a closed loop must be zero.

StarStarStarStar

Electric Field

StarStarStarStar

An electric field is a vector field around charged particles that represents the force exerted on other charged particles, defined as E=Fq\vec{E} = \frac{\vec{F}}{q}, where F\vec{F} is force.

StarStarStarStar

Capacitance

StarStarStarStar

Capacitance is the ability of a system to store an electric charge, defined as C=QVC = \frac{Q}{V}, where QQ is the charge and VV is the voltage.

StarStarStarStar

Lenz's Law

StarStarStarStar

Lenz's Law states that the direction of the induced current is such that it opposes the change in magnetic flux that produced it, as defined by Faraday's law.

StarStarStarStar

Gauss's Law

StarStarStarStar

Gauss's Law relates the electric flux through a closed surface to the charge enclosed by that surface: EdA=Qencε0\oint \vec{E} \cdot d\vec{A} = \frac{Q_{enc}}{\varepsilon_0}.

StarStarStarStar

Electrical Resistance

StarStarStarStar

Electrical resistance is a measure of the degree to which an object opposes the passage of an electric current, R=ρlAR = \rho\frac{l}{A}, where ρ\rho is resistivity.

StarStarStarStar

Coulomb's Law

StarStarStarStar

Coulomb's Law quantifies the amount of force between two stationary, electrically charged particles: F=keq1q2r2F = k_e \frac{|q_1 q_2|}{r^2}.

StarStarStarStar

Electromagnetic Waves

StarStarStarStar

Electromagnetic waves are waves of electric and magnetic fields that transport energy and travel through space at the speed of light, governed by Maxwell's equations.

StarStarStarStar

Ampere's Law

StarStarStarStar

Ampere's Law relates the integrated magnetic field around a closed loop to the electric current passing through the loop: Bdl=μ0Ienc\oint \vec{B} \cdot d\vec{l} = \mu_0 I_{enc}.

StarStarStarStar

Electric Potential

StarStarStarStar

Electric potential is the amount of electric potential energy per unit charge at a point in a static electric field, V=UqV = \frac{U}{q}.

StarStarStarStar

Joule's Law

StarStarStarStar

Joule's Law deals with the heat produced by an electric current, expressed as P=I2RP = I^2R, where PP is power.
