TOROIDS
Toroidal transformers are insulated, ring-shaped coils that operate within electronic circuits. Transformers change an alternating current voltage from one level to the next without the need for moving parts. Toroidal transformers have advantages over other shaped transformers. A toroid is more efficient than a traditional transformer, and the toroidal transformer takes up less space.

Applications and Industries
A toroidal transformer is used when working with electricity that has a low frequency. A toroid functions as an inductor, which boosts frequencies to appropriate levels. Toroidal transformers are frequently used for many different applications that include:
- Medical
- Military
- Electronics
- Industrial
- And more
