electric charge, coulomb's law, electric fields, and electric flux

Static electricity

an example of this is when you remove your clothes from the dryer where many, but not all of them, stick together.

Electric charges

determines how strong the interaction between the two charged objects, whether it is positive or negative

law of charges

like charges repel each other, and unlike charges attract each other.

Coulomb (C)

The charges of subatomic particles are measured in terms of elementary charges or e.

1 C = 6.242 × 10^18e

The relationship of e and coulomb

Conductors

are the materials which charges can move freely. In contrary, nonconductors are commonly called insulators, are those who has the opposite property — charges cannot move freely.

Insulators

also called nonconductors and it is where charges cannot move freely

Charging by conduction

consider two neutrally charged objects, A and B. The charges of A is evenly distributed throughout the whole material. But when a strongly negative object is brought near A, the negative charges of A will move farther from where B is. Subsequently, the opposite charge (positive) of A will be attracted to the side near B.

a process where a neutral object becomes charged through direct physical contact with a charged object.

Charging by induction

a method of charging an object without direct physical contact with a charged object. It involves bringing a charged object near a neutral conductor, causing a redistribution of charges within the conductor due to electrostatic forces, a process known as polarization.
