vastajännitetty
Vastajännitetty is a Finnish term that translates to "contrary voltage" or "countervoltage." It refers to an induced voltage that opposes the change in current that produced it. This phenomenon is a fundamental principle in electromagnetism, particularly in inductors and transformers.
When the current flowing through an inductor changes, it creates a changing magnetic field. This changing magnetic
In practical terms, vastajännitetty is responsible for the inductive reactance of a circuit, which limits the
