Sähkövarauksiltaan

Sähkövarauksiltaan is a Finnish term that translates to "electrically charged" or "possessing electric charge" in English. It is used to describe objects or particles that have accumulated or possess a net electrical charge. This charge can be positive, negative, or neutral, though the term often implies a deviation from a neutral state.

In physics, electric charge is a fundamental property of matter that causes it to experience a force when placed in an electromagnetic field. The SI unit of electric charge is the coulomb (C). Objects become electrically charged through processes such as friction (triboelectric effect), conduction, or induction. For instance, rubbing a balloon on hair can cause the balloon to become negatively charged, while the hair becomes positively charged.

A body that is sähkövarauksiltaan neutral has an equal number of positive and negative charges, resulting in no net electrical effect. Conversely, a body that is sähkövarauksiltaan positive has a deficiency of electrons, while a body that is sähkövarauksiltaan negative has an excess of electrons. The behavior of charged objects is governed by Coulomb's law, which states that like charges repel each other, and opposite charges attract each other. Understanding electric charge is fundamental to comprehending many phenomena in electricity and magnetism.
