Coulomb

SI unit of charge

New cards

3

Electric charge

It is a fundamental property of matter that arises from the presence or absence of electrons in an atom.

New cards

4

Conductors

These are materials that allow electric charge to flow freely through them.

New cards

5

Insulators

These are materials that do not allow electric charge to flow easily.

New cards

6

law of electrostatics

a set of fundamental principles that govern the behavior of electric charges at rest.

New cards

7

Coulomb's law

This law states that the force between two point charges is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.

New cards

8

Electric field

A region in space where an electric charge experiences a force.

New cards

9

Electric potential difference

It is the difference in electric potential between two points in an electric field. It is measured in volts (V).

New cards

10

Charging

It is the process of adding electrical energy to a system.

22

Electric potential energy

It is the energy that a charged particle possesses due to its position in an electric field. It is defined as the amount of work required to move a charged particle from infinity to a point in the electric field.

New cards

23

Joule

SI unit of electric potential energy

New cards

24

Potential difference

It is the difference in electric potential energy per unit charge between two points in an electric circuit.

New cards

25

Gauss' Law

It is a fundamental principle in electromagnetism that relates the electric flux through a closed surface to the charge enclosed within that surface. It is named after the German mathematician and physicist Carl Friedrich Gauss.

New cards

26

Flux

It is the amount of a physical quantity passing through a given surface.

New cards

27

Extended charge distributions

This refer to the distribution of electric charge over a three-dimensional object.

New cards

28

Continuous Charge Distributions

These charge distributions are those where the charge is distributed continuously over a volume or surface.

New cards

29

Spherical Charge Distributions

These charge distributions are those where the charge is distributed uniformly over the surface of a sphere.

New cards

30

Cylindrical Charge Distributions

These charge distributions are those where the charge is distributed uniformly over the surface of a cylinder.

New cards
