In signal processing, which unit is typically used to express inductance?

• A. The coulomb
• B. The volt
• C. The ohm
• D. The henry

Answer: (D)

Inductance is measured in henries. This unit is named after Joseph Henry, who made significant contributions to the understanding of electromagnetism. One henry is defined as the inductance of a circuit in which a change in current of one ampere per second induces an electromotive force of one volt. This relationship highlights the fundamental workings of inductors in electrical circuits, where the inductance specifies how much electromotive force is generated for a given rate of change of current. In contrast, the other options represent different electrical concepts: the coulomb is a unit of electric charge, the volt measures electric potential, and the ohm quantifies electrical resistance. Thus, in the context of signal processing and related electrical concepts, henries clearly denote the unit relevant to inductance.
