Inductor acts as Short Circuit in DC

Introduction:
In electrical circuits, an inductor is a passive electronic component that stores energy in a magnetic field when electric current flows through it. Inductors are widely used in electrical circuits for various applications such as filtering, tuning, and energy storage.

Behavior of Inductor in DC Circuit:
In a DC circuit, the inductor behaves differently than in an AC circuit. In a DC circuit, when the current starts flowing through an inductor, the magnetic field around the inductor starts building up. This magnetic field opposes the change in current, which means the inductor tries to maintain the current flow. As a result, the inductor acts as a short circuit to DC current.

Explanation:
The inductor has a property called inductance, which is a measure of its ability to store energy in a magnetic field. When there is a change in current, the inductor opposes the change by creating a back EMF (electromotive force) that opposes the applied voltage. In an AC circuit, this opposition to the change in current causes the inductor to impede the flow of current, and it acts as an open circuit.

However, in a DC circuit, the current is constant, and there is no change in current. Therefore, the inductor does not oppose the current flow, and it behaves like a short circuit. This means that the inductor has a very low resistance to DC current and allows it to flow freely through the circuit.

Conclusion:
In conclusion, in a DC circuit, an inductor acts as a short circuit, and in an AC circuit, it acts as an open circuit. Understanding the behavior of inductors in different circuits is important for designing and analyzing electrical circuits accurately.
