The reactance of an inductor in a dc circuit is zero.
For dc → f = 0
XL = 2π f L
XL = 0
Therefore, the reactance of an inductor in a dc circuit is zero.
For dc → f = 0
XL = 2π f L
XL = 0
Therefore, the reactance of an inductor in a dc circuit is zero.

Understanding Inductor Reactance in DC Circuits
In a DC circuit, the behavior of an inductor is unique due to its properties. Let’s break down the concept of reactance in this context.
What is Reactance?
- Reactance is the opposition that an inductor or capacitor offers to the change of current or voltage.
- It is frequency-dependent, affecting AC circuits primarily.
Inductor Behavior in DC Circuits
- When a DC voltage is applied, the inductor initially opposes the change in current.
- Over time, as the current stabilizes, the inductor acts like a short circuit.
Inductor Reactance in DC
- The formula for inductive reactance (X_L) is given by:
X_L = 2πfL
where:
- f = frequency (Hz)
- L = inductance (Henries)
- In a DC circuit, the frequency (f) is 0 Hz since DC does not have alternating current.
Conclusion: Zero Reactance
- Therefore, substituting f = 0 in the reactance formula results in:
X_L = 2π(0)L = 0
- This means that the reactance of an inductor in a DC circuit is indeed zero.
Final Answer
- The correct answer is option 'C': Zero. This indicates that once the current stabilizes, the inductor does not resist the flow of DC current, allowing it to pass freely.
