Which of the following is a property of inductance?

• A. Resists change in voltage
• B. Resists change in current
• C. Stores electrical energy
• D. Measures capacitance

Answer: (B)

Inductance is defined as the property of an electrical component, typically a coil or inductor, that causes it to resist changes in current. When the current flowing through an inductor changes, the inductor generates a counter electromotive force (EMF) that opposes the change, due to the magnetic field created around it. This behavior is a fundamental principle of inductance and is crucial in the design of electrical circuits, especially in AC (alternating current) applications where current frequently changes direction and magnitude.

The relationship between inductance and current is governed by Faraday's law of electromagnetic induction, which highlights how a changing current can induce a voltage in the opposite direction. As a result, inductors are widely used in filters, oscillators, and transformers to control and manipulate current in various electrical applications.

Understanding that inductance resists change in current helps explain the role of inductors in power management and signal filtering in electronic circuits.
