Electric charge can be defined as a fundamental property of subatomic particles that gives rise to

the phenomenon of experiencing force in the presence of electric and magnetic fields.

These fields exert influence on charged particles, resulting in observable effects.

Electric charge comes in two main types: positive and negative charges.

Positive charges are associated with protons, which are subatomic particles residing in the nucleus of an atom.

They are represented by the symbol “+”.

On the other hand, negative charges are linked to electrons, which orbit the atomic nucleus and are denoted by the symbol “-“.

When an object carries a negative charge, it possesses an excess of electrons compared to protons.

Conversely, a positive charge indicates an deficiency of electrons comapre to protons.

Opposite charges, such as positive and negative, attract each other, while like charges,

such as positive and positive or negative and negative, repel each other.
