Inductors behaves like the:
Correct answer: B. Resistors in A.C circuit
- A. Resistors in D.C circuit
- B. Resistors in A.C circuit
- C. Both (a) and (b)
- D. None of these
Explanation
In an AC circuit, the behavior of an inductor is often compared to that of a resistor. This comparison is due to the fact that inductors, like resistors, impede the flow of current. However, the nature of their impedance is different.Resistors directly resist the flow of current by dissipating energy in the form of heat, irrespective of whether it's an AC or DC circuit.Inductors in an AC circuit behave similarly to resistors in terms of opposing the flow of current, but their impedance arises due to the inductive reactance caused by the changing magnetic field induced by the alternating current.So, in terms of impeding current flow, the behavior of an inductor in an AC circuit is often likened to that of a resistor. Therefore, the correct answer is indeed "Resistors in AC circuit".

About Electromagnetic Induction
Changing magnetic flux induces an emf according to Faraday's law, while Lenz's law gives the direction that opposes the change producing it. Transformers apply induction between coils to step alternating voltage up or down, with turns ratio, current transformation and energy losses determining practical operation.
