- Inductors are passive components that store energy in magnetic fields. When AC current is passed through an inductor the magnetic field due to the current can cause self-induction. This will generate an emf that will oppose the current flow.
- The self-induced emf on an inductor is given by,
Here L is the inductance and is the change in current.
