JEE Main 4 April 2024, Shift 2, Physics Q44

Question 44 of 90 in this shift, Physics question 14 of 30, Section A.

Match List I with List II LIST I | LIST II A. Purely capacitive circuit | I. [figure: phasor diagram, II along the vertical axis (up) and VV along the horizontal axis, with a 90∘90^\circ angle marked between them] B. Purely inductive circuit | II. [figure: II and VV phasors along the same horizontal line, both pointing right (in phase)] C. LCR series at resonance | III. [figure: II along the horizontal axis and VV drawn at an angle θ\theta above it] D. LCR series circuit | IV. [figure: VV along the vertical axis (up) and II along the horizontal axis, with a 90∘90^\circ angle marked between them] Choose the correct answer from the options given below:

The figure, in words

List II entries are phasor diagrams: I: I vertical (up), V horizontal, 90 degrees marked; II: V and I collinear along the horizontal; III: I horizontal, V at angle theta above it; IV: V vertical (up), I horizontal, 90 degrees marked.
