In what unit is inductance measured?

• A. Volts
• B. Amps
• C. Henry's
• D. Watts

Answer: (C)

Inductance is measured in henrys. This unit quantifies the ability of a coil or inductor to store energy in a magnetic field when an electric current passes through it. One henry is defined as the amount of inductance in a coil when the change in current through the coil induces an electromotive force (EMF) of one volt. This relationship highlights the fundamental characteristics of inductors in circuits, particularly their role in resisting changes in current.

The other choices represent different electrical parameters: volts measure electric potential, amps measure electric current, and watts measure power. Each of these units serves distinct purposes in the field of electricity and electromagnetism, but they do not relate to the property of inductance, which is exclusively specified in henrys.
