What unit is used to measure inductance?

• A. Farads
• B. Henrys
• C. Ohms
• D. Watts

Answer: (B)

Inductance is measured in Henries, which is the standard unit for this electrical property. The Henry is defined as the amount of inductance required to induce one volt of electromotive force when the current flowing through the inductor changes at the rate of one ampere per second. This is a fundamental concept in electromagnetism and is critical for understanding how inductors work in circuits, particularly in applications involving alternating current (AC) where inductive reactance plays a significant role. The other units do not measure inductance. Farads are used to measure capacitance, Ohms measure resistance, and Watts measure power. Understanding these distinctions is important for grasping the basics of electronics and the behavior of different circuit components, including inductors.
