What is the basic unit of measure for inductance?

The basic unit of measure for inductance is the Henry. Inductance is a property of an electrical circuit that opposes changes in electric current and is primarily associated with inductors, which are passive electrical components used to store energy in a magnetic field when electric current flows through them.

The Henry is defined as the amount of inductance required to induce one volt of electromotive force when the current through the inductor changes at the rate of one ampere per second. This definition highlights the relationship between voltage, current, and the rate of change of current, which are fundamental concepts in electromagnetism and circuit theory.

Understanding inductance and its measurement is crucial for applications involving alternating current (AC) and in the design of circuits that include motors, transformers, and various filtering elements in electronic devices.
