Henry

Henry is a unit of measurement in physics, specifically in the field of electromagnetism. It is used to quantify inductance, which is a property of electrical circuits that describes how well an electrical conductor can store energy in a magnetic field when an electric current passes through it. One henry is defined as the amount of inductance required to induce one volt of electromotive force when the current changes at a rate of one ampere per second. Named after the American scientist Joseph Henry, this unit is important in designing electrical systems like transformers and motors.
