Vaihtovirtajärjestelmien
Vaihtovirtajärjestelmä, often referred to as AC (Alternating Current) system, is an electrical system where the direction of electric current reverses periodically. This contrasts with direct current (DC) systems where the current flows in only one direction. The primary advantage of AC systems lies in their ability to be easily transformed to different voltage levels using transformers. This makes it efficient to transmit electricity over long distances at high voltages, reducing energy loss, and then step down the voltage to safer levels for use in homes and businesses.
The generation of AC typically occurs in alternators, which are electrical generators that produce alternating voltage
The widespread adoption of AC systems is largely due to the pioneering work of Nikola Tesla and
