Sähkövirtapiiri
Sähkövirtapiiri, also known as an electrical circuit, is a closed loop through which an electric current can pass. It consists of various components such as resistors, capacitors, inductors, and switches, connected in series or parallel configurations. The fundamental principle governing electrical circuits is Ohm's Law, which states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them.
Electrical circuits can be classified into two main types: direct current (DC) and alternating current (AC).
The behavior of electrical circuits can be analyzed using various techniques, including Kirchhoff's laws, which describe
In summary, sähkövirtapiiri is a fundamental concept in electrical engineering, encompassing the principles and components that
