Elektrilaengud, often translated as electric charges, are a fundamental property of matter. They are quantized, meaning they come in discrete units, and are the source of all electromagnetic phenomena. There are two types of electric charge: positive and negative. Like charges repel each other, while opposite charges attract. The smallest known unit of electric charge is the elementary charge, denoted by the symbol e, which is carried by a single proton (positive) or an electron (negative). The charge of an electron is approximately -1.602 x 10^-19 coulombs, and the charge of a proton is approximately +1.602 x 10^-19 coulombs.
In most materials, electric charge is carried by electrons. In conductors, such as metals, electrons are loosely
The concept of electric charge is crucial for understanding electricity, magnetism, and the structure of atoms
