tasavirtasähköä
Tasavirtasähkö, also known as direct current (DC) electricity, is a type of electrical current that flows in only one direction. This is in contrast to alternating current (AC), where the direction of the current periodically reverses. In a DC circuit, electrons move from a region of lower potential (negative terminal) to a region of higher potential (positive terminal).
Common sources of tasavirtasähkö include batteries, fuel cells, and solar panels. These devices convert chemical or
Tasavirtasähkö is essential for many electronic devices, such as smartphones, laptops, and LED lights. These devices
