Inductive components are electrical devices that store energy in a magnetic field when an electric current flows through them. The most common types of inductive components are inductors and transformers. Inductors are typically used in circuits to filter signals or store energy, while transformers are used to change voltage levels in power systems. These components are characterized by their inductance, which is measured in henries. Inductance determines how much energy can be stored and how the component reacts to changes in current. Inductive components play a crucial role in various applications, including power supplies, radio transmitters, and signal processing.
