Electrical inductance is best defined as the property of a conductor that opposes changes in current flow. This phenomenon occurs when the flow of electric current through a conductor creates a magnetic field around it. When there are changes in this current, the magnetic field also changes, which induces a voltage in the opposite direction—this is known as self-inductance. This ability to resist changes in current is a fundamental characteristic of inductors and is critical in applications such as transformers, motors, and various types of circuits where stabilization of current is necessary.

The other options refer to different concepts in electrical theory. The first option talks about lack of current flow, which does not align with the definition of inductance. The second option refers to resistance to voltage changes, which is more pertinent to capacitance or resistance in a circuit, rather than inductance. The last option describes electric charge storage, which relates to capacitors, not inductors. Therefore, the definition of inductance as the property that opposes changes in current flow captures its essence and application accurately within electrical systems.
