Which unit is used to measure inductance?

• A. Joule
• B. Henry
• C. Ohm
• D. Farad

Answer: (B)

Inductance is a property of electrical circuits that describes the ability of a conductor to store energy in a magnetic field when an electric current flows through it. The standard unit used to measure inductance is the Henry. One Henry is defined as the amount of inductance required to induce one volt of electromotive force when the current through the inductor changes at a rate of one ampere per second. Other units mentioned in the choices are related to different electrical properties. Joules measure energy, Ohms measure resistance, and Farads measure capacitance. Each of these units defines a distinct characteristic of electrical circuits, but only the Henry pertains specifically to the measure of inductance. Therefore, understanding inductance and its measurement is critical for applications involving inductors, transformers, and other components where magnetic fields are involved in energy storage and transfer.
