Introduction to Inductors & Chokes

Inductors and chokes are two of the most commonly used components in electrical and electronics engineering. They are used for storing energy in a magnetic field, filtering signals, and controlling the flow of electrical current in a circuit. What are Inductors &...

How Toroidal Electrical Transformers Work

Electrical transformers are essentially a coil of electrically conductive wire wound around an iron core, most often a rectangular “EI” core. Some transformers, however, look more like a doughnut, and they are called toroidal transformers. Either construction makes...
