Explore the properties of electric charge, including positive and negative charges, repulsion and attraction, Coulomb's law, the coulomb unit, and charge quantization.
Learn how an area vector converts a scalar area into a vector by using the outward normal, with magnitude equal to surface area, such as a yz-plane area along x.
Learn how electric flux quantifies the electric field through a surface, using the dot product with the surface area vector to relate field strength to distance from charge.
Compute the electric flux through a 20 cm^2 plane with E = (3,6,4) by orienting the area vector along the x-axis, converting to m^2, and using Φ = E·A, yielding 6.0×10^-3.
Apply Gauss's law to relate the flux through a closed surface to the enclosed charge, using phi equals Q over epsilon naught in vacuum.
Learn to pick a Gaussian surface that either encloses all charges or none, avoiding discrete charges, and use perpendicular or constant fields to simplify the flux calculation.
Static Electricity, also known as Electrostatics, is the first topic within the broader electromagnetism category.
