ACmotstanden
ACmotstanden is a term that refers to the opposition to alternating current (AC) flow in an electrical circuit. This opposition is a fundamental property of electrical circuits and is distinct from simple resistance, which primarily affects direct current (DC). ACmotstanden encompasses several phenomena that arise due to the constantly changing direction and magnitude of the AC voltage and current.
The primary components contributing to ACmotstanden are resistance, inductive reactance, and capacitive reactance. Resistance, as in
The combined effect of these three components is known as impedance, often represented by the symbol Z.
