Coil Circuit Symbol - Circuit Diagram

Coil circuit symbols have been around for hundreds of years, but it wasn’t until recently that they’ve become an essential part of our modern electrical design. A coil circuit symbol is a visual representation of an electrical component or device that contains a coil. It denotes the presence of an inductor, which is any type of component made from two or more windings of insulated wire that can store energy in a magnetic field when current is applied to the windings.

The coil circuit symbol itself looks quite complicated and may be somewhat intimidating to those unfamiliar with the basics of electrical engineering. However, when understood, the coil symbol can be quite invaluable in quickly identifying components within a schematic diagram. The figure below provides an example of a schematic diagram containing a few various coil circuit symbols.

The primary purpose of using a coil circuit symbol is to indicate the presence of an inductor in the electrical design. Inductors are widely used in electrical systems for things like voltage filtering, signal shaping, or energy storage. Furthermore, in certain applications, coils may also be used as part of a transformer, where they can be used to move energy across two or more circuits. As a result, it’s important to have a visual representation of the coil’s presence in order to properly convey how the system functions.

Given their importance in electrical engineering, it’s no surprise that coil circuit symbols have been around for so long. Not only do they provide a quick way to identify the presence of an inductor, but they also provide a means for conveying the function of various components in an electrical system. Whether you’re an experienced engineer or just getting started with electrical design, coil circuit symbols can be an invaluable asset.
