What is the property of an electrical circuit that opposes any change in current?

Inductance is the property of an electrical circuit that opposes any change in current. It arises in circuits containing inductors, which store energy in a magnetic field when an electric current passes through them. When the current flowing through an inductor changes, it generates a back electromotive force (emf) that opposes that change, according to Lenz's Law. This behavior is fundamental to inductors and can be observed in various applications, including transformers and electrical filters.

Resistance, on the other hand, primarily opposes the flow of current rather than changes in current. Capacitance relates to the ability to store electric charge and does not directly oppose changes in current in the same way inductance does. Voltage represents the electric potential difference and is not a property related to opposing changes in current. Each of these concepts plays a unique role in electrical engineering, but when it comes to opposing changes in current specifically, inductance is the key factor.
