Electric charge is a fundamental property of matter that causes it to experience a force when placed in an electromagnetic field. Charges are either positive or negative and are measured in coulombs (C).

The SI unit of electric charge is the coulomb (C).
Protons carry a positive charge, while electrons carry a negative charge.
Like charges repel each other, whereas opposite charges attract.
The principle of conservation of charge states that the total electric charge in an isolated system remains constant.
Electric charge is quantized, meaning it comes in discrete amounts typically multiples of the elementary charge \( e = 1.602 \times 10^{-19} \) C.
