Om strömmen genom en induktiv krets varierar kommer en spänning att uppstå över den induktiva komponenten som är proportionell mot den magnetiska flödesändringen per tidsenhet där minustecknet beror på att induktansen motverkar ändringen av strömmen. En induktans orsakar en fasskillnad mellan spänning och ström. Denna fasvridning är positiv för en induktiv krets, det vill säga, fasmässigt kommer spänningen att ligga före strömmen. En passi…

SOLENOIDS. It is possible to calculate L for an inductor given its geometry (size and shape) and knowing the magnetic field that it produces. This is difficult in most cases, because of the complexity of the field created. …
Inductors are passive electronic components that store energy in their magnetic field when an electric current flows through them. They are often used in electrical and …
Energy stored in an inductor is the electrical energy accumulated in the magnetic field created by the flow of current through the inductor. When current passes through the inductor, it generates …
