suorasähköiset
Suorasähköiset refers to a Finnish term that translates to "direct current" or "DC" in English. Direct current is an electric current that flows in only one direction. This is in contrast to alternating current (AC), where the direction of flow reverses periodically. In a DC circuit, the electric charge flows from the positive terminal to the negative terminal.
Sources of direct current include batteries, fuel cells, and solar cells. Many electronic devices, such as smartphones,
Despite the dominance of AC in grid-level distribution, DC remains crucial for specific applications. It is
