Enclosures
These are the two most common shapes for Gaussian Surfaces.
What are a Sphere and a Cylinder?
A physical phenomenon created by a charge; it “transmits” a force between two charges.
What is an Electric Field?
This greek letter is typically used to represent flux, both electric and magnetic.
What is (Capital) Phi?
This equation gives the relationship between the current through and voltage across a resistor.
What is Ohm's Law (V=IR)?
This common technique helps us find the direction of the Magnetic Force on a charge moving through a magnetic field.
What is the Right Hand Rule?
This kind of material possesses no inner Electric Field in Electrostatic Equilibrium.
What is a Conductor?
An intrinsic property of a material, independent of its shape or size, directly proportional to the resistance, and denoted by ρ.
What is Resistivity?
This fundamental constant is included in the definition for the Permeability of Free Space.
What is Pi?
When a voltage is applied to an uncharged capacitor, it can be modeled as this.
What is a Short Circuit / Straight Wire?
This phenomenon consists of light rays combining constructively and destructively to form a repeated pattern.
What is Interference?
These electronic components store energy inside of electric and magnetic fields, respectively.
What are Capacitors and Inductors?
The set of four equations that comprise a complete, overarching theory of electromagnetism.
What are Maxwell's Equations?
This fundamental constant is equal to approximately 8.85x10^-12 C^2/Nm^2.
What is the Permittivity of Free Space (Lowercase Epsilon)?
This quantity is the ratio of the voltage across to the current through both capacitors and inductors.
What is Reactance?
This common form of Potential Difference is the work done on a charge per unit charge.
What is the Electromotive Force (EMF)?
This is the magnitude of the Magnetic Field on the outside of an ideal solenoid.
What is Zero?
For a material, the ratio of the speed of light in a vacuum to that in a material.
What is the Index of Refraction?
This common unit in Magnetics is equal to 1 kg*m^2/A^2*s^2.
What is a Henry?
This driving frequency causes an AC Circuit to exhibit its maximum possible current flow.
What is the Resonant Frequency?
This is the generic equation for the Electric Field of an EM Wave traveling in the x-direction.
What is E_y = E_0*cos( k*x - omega*t )?
This imaginary shape considers only how much current is flowing inside of it.
What is an Amperian Loop?
The creation of voltage across a current-carrying conductor by a magnetic field.
What is the Hall Effect?
This is the Coulomb charge of an Electron.
What is -1.602*10^-19 C?
This is the equation for the Impedance of an RLC Circuit.
What is Z = SQRT[R^2 + (X_L - X_C)^2]?
This is your favorite part of the course.
