Inductors, coils, and chokes are passive electrical components that are used to store and control electrical energy in a circuit. Inductors, coils, and chokes are made by winding a conductor, such as a wire or strip of metal, into a coil or other shape. When an electrical current flows through an inductor, it creates a magnetic field around the coil. This magnetic field can then store energy, and release it back into the circuit when the current changes. Inductors, coils, and chokes are commonly used in a wide range of electronic circuits, including filters, oscillators, and power supplies. They are available in a variety of sizes, styles, and performance levels, depending on the specific application and requirements. Inductors, coils, and chokes are an essential component of many electronic systems, and play a key role in controlling the flow of electrical energy in a circuit.
