Coulomb's constant
Johann Carl Friedrich Gauss
Gauss' law was formulated by?
Capacitors
It is a passive two terminal (positive and negative polarities) electrical component that stores potential energy in an electric field.
Gauss Law
It is an expression of the general relationship between the net electric flux through a closed surface and the charge enclosed by the surface.
Electricity
is a type of energy that consists of the movement of electrons between two points when there is a potential difference between them, making it possible to generate what is known as an electric current.
Electric Potential Energy
is the energy that is needed to move an electric charge against an electric field
Coulomb's Law
is the force of attraction or repulsion between two charged bodies is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. measures the electrostatic force that acts between charges in one space.
Electric potential energy
t is the energy that is needed to move an electric charge against an electric field.
Electric Charge
If an atom has more or less electrons than protons, that atom acquires an
Maximum
If electric flux = EA, this means the electric flux is at ____________.
Zero
If 𝜱 = 𝑬𝑨𝐜𝐨𝐬𝟗𝟎°,this means the 𝜱 is equal to _______.
Electric Potential
It is the amount of work needed to move an electric charge from its reference point to a specific point on the electric field.

negative charge
excess of electrons
Electrostatics
is the interaction between electric charges that are at rest.
electric field lines
lines that represent both the magnitude and the direction of the electric field
electrically neutral
