Which of the following statements is true regarding inductors?

Inductors are components in an electrical circuit that primarily function to oppose changes in current. This property is due to the principle of electromagnetic induction, where a changing current in the inductor generates a magnetic field, which in turn induces a voltage that opposes the change in current. This is described by Lenz's law, highlighting that inductors resist abrupt changes in the flow of current, helping to stabilize circuit conditions.

While other statements touch on different aspects of electrical components, they do not accurately define the primary role of inductors. For instance, energy storage in passive components like capacitors is related to electric fields, while inductors store energy in magnetic fields. The measurement unit for capacitance is Farads, but inductors are measured in Henries. Amplification of signals is typically the function of active components like transistors, rather than inductors.
