1. Electrical Circuits and Components:
Understanding self-inductance helps design inductors, which are essential
components in electrical circuits, including:

Filters:
Inductors are used in low-pass filters to block high-frequency signals while allowing lowfrequency signals to pass.

Transformers:
Self-inductance principles are crucial in creating efficient transformers for voltage and
current regulation.

Energy Storage:
Coils are used in inductive energy storage systems, such as flywheel energy storage in
modern grids.
