elektrilaengusid
Elektrilaengud, or electric charges, are fundamental properties of matter that arise from the presence of electrons within atoms. These charges can be either positive or negative, with electrons carrying a negative charge and protons carrying a positive charge. The magnitude of an electric charge is quantized, meaning it occurs in discrete units known as the elementary charge, which is approximately 1.602 x 10^-19 coulombs.
Electric charges exert forces on each other, following Coulomb's law, which states that the force between two
Electric charges are conserved, meaning the total charge within an isolated system remains constant over time.
In practical applications, electric charges are harnessed to generate electricity, power electronic devices, and facilitate various
