Which unit represents inductance?

Which unit represents inductance?

• A. Henry
• B. Farad
• C. Siemens
• D. Volt

Answer: (A)

Inductance is the property of an electrical circuit that opposes changes in electric current. The unit of measurement for inductance is the Henry. This unit is named after the American inventor Joseph Henry, who made significant contributions to the fields of electromagnetism and self-induction. In practical terms, one Henry is defined as the amount of inductance required to induce an electromotive force (EMF) of one volt in a circuit when the current through that circuit changes at a rate of one ampere per second. This relationship highlights the fundamental nature of inductance in terms of its effect on current and voltage. The other options provided refer to different electrical characteristics: capacitance is measured in Farads, conductance in Siemens, and electromotive force in Volts. Each of these units pertains to different aspects of electrical theory and practice, but they are not applicable to inductance, making the Henry the correct and relevant choice in this context.
