STANDARD Physics Impedance MCQ Question
The graphs given below depict the dependence of two reactive impedances X₁ and X₂ on the frequency of the alternating e.m.f. applied individually to them. We can then say that:
X₁ is an inductor and X₂ is a capacitor
X₁ is a resistor and X₂ is a capacitor
X₁ is a capacitor and X₂ is an inductor
X₁ is an inductor and X₂ is a resistor
Correct Answer
Detailed Explanation
The graph for X₁ shows a decrease in impedance with increasing frequency, characteristic of a capacitor (Xₚ = 1/(2πfC)). The graph for X₂ shows an increase in impedance with increasing frequency, characteristic of an inductor (Xₗ = 2πfL).
