Ohm's Law
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 .
Faraday's Law of Electromagnetic Induction
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: .
Lorentz Force
The Lorentz force is the force exerted on a charged particle moving through an electric and magnetic field: .
Series and Parallel Circuits
In series circuits, components are connected end-to-end, while in parallel circuits, they are connected alongside each other, affecting resistance and current flow.
Inductance
In inductance, a change in current in one coil will induce a voltage in a neighboring coil, defined as .
Magnetic Field
A magnetic field is a vector field that describes the magnetic influence on moving electric charges, materials, and currents.
Magnetic Flux
Magnetic flux is a measure of the amount of magnetic field passing through a given area, defined as .
Maxwell's Equations
Maxwell's Equations are a set of four equations that form the foundation of classical electrodynamics, classical optics, and electric circuits.
Kirchhoff's Current Law
Kirchhoff's Current Law states that the total current entering a junction must equal the total current leaving the junction.
Kirchhoff's Voltage Law
Kirchhoff's Voltage Law states that the sum of all voltages around a closed loop must be zero.
Electric Field
An electric field is a vector field around charged particles that represents the force exerted on other charged particles, defined as , where is force.
Capacitance
Capacitance is the ability of a system to store an electric charge, defined as , where is the charge and is the voltage.
Lenz's Law
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.
Gauss's Law
Gauss's Law relates the electric flux through a closed surface to the charge enclosed by that surface: .
Electrical Resistance
Electrical resistance is a measure of the degree to which an object opposes the passage of an electric current, , where is resistivity.
Coulomb's Law
Coulomb's Law quantifies the amount of force between two stationary, electrically charged particles: .
Electromagnetic Waves
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.
Ampere's Law
Ampere's Law relates the integrated magnetic field around a closed loop to the electric current passing through the loop: .
Electric Potential
Electric potential is the amount of electric potential energy per unit charge at a point in a static electric field, .
