AIIMS 2019 Physics AC Circuits MCQ Question

In an LCR circuit, the phasor diagram illustrates the relationship between the voltage and current across the inductor (L), capacitor (C), and resistor (R). Option B is correct because it accurately represents the phase differences, showing that the total voltage phasor is the vector sum of the individual voltage phasors across each component, which is essential for understanding impedance and resonance in AC circuits. The other options are incorrect as they may misrepresent the phase relationships or fail to include critical components of the circuit, leading to an incomplete understanding of the circuit's behavior. Understanding these phase relationships is crucial for analyzing how reactive components affect overall circuit performance.
