Sähkövarauksina

Sähkövarauksina refers to electric charges in Finnish. Electric charge is a fundamental property of matter that causes it to experience a force when placed in an electromagnetic field. There are two types of electric charge: positive and negative. Like charges repel each other, while opposite charges attract. The smallest unit of electric charge is the elementary charge, denoted by 'e', which is the magnitude of the charge of a single proton or electron. Protons carry a positive charge, while electrons carry a negative charge. Atoms are electrically neutral because they contain an equal number of protons and electrons. When an atom gains or loses electrons, it becomes an ion, acquiring a net positive or negative charge, respectively. Electric charge is conserved, meaning it cannot be created or destroyed, only transferred from one object to another. The SI unit of electric charge is the coulomb (C). The movement of electric charge is known as electric current, a fundamental concept in electricity and electronics. Understanding electric charge is crucial for comprehending phenomena like static electricity, magnetism, and the behavior of electrical circuits.
