Static electricity

Gaussian surface: A closed surface imagined around a charge

Electron volt: amount of work done to remove an electron from one point to another point

Gauss’s law: flux is 1/Ɛo times of charge

Dielectric constant: ratio of force without medium and with medium

Point charge: charge present in a point body

Electric dipole: The system that acts for two equal but opposite charge at a short distance

Electric intensity: force felt by a single positive charge placed at a point

Charge quantization: charge is always integer multiple of number of electrons

Capacitance: amount of charge required to increase potential by one unit [C=q/v]

Coulomb: amount of electric charge carried by one ampere current in one second [Q=it]

Electric flux: The number of lines of force passing perpendicularly through an Electric field

Surface charge density: amount of charge per unit area [sigma=q/A]

Farad: 1 coulomb charge in 1 volt electric potential [C=q/v]

Electric dipole moment: product of a charge and the distance between them [p=2l×q]

Electric potential: The amount of work done to bring a unit positive charge from a point of infinity to the electric field

Dielectric medium: The non conducting medium between 2 charges
