Transformer and inductor components are electronic components that use electromagnetic induction to transfer electrical energy between circuits. A transformer is an electrical device that consists of two or more windings, or coils of wire, that are magnetically coupled. When an alternating current flows through the primary winding, it creates a changing magnetic field that induces a voltage in the secondary winding, allowing electrical energy to be transferred between the two windings. An inductor is a type of transformer that has only one winding and is used to store energy in the form of a magnetic field. Inductor components are commonly used in electronic circuits to filter signals, regulate voltage, and perform other functions.
