NEET 2023 Phase 1 · PhysicsImpedancePrevious Year Question
The net impedance of circuit (as shown in figure) will be (series circuit with R = 10 Ω, an inductor and a capacitor driven by an AC source; from the figure values X_L = 5 Ω and X_C = 10 Ω).
Answer: (C) 5√5 Ω. Answer: (C) 5√5 Ω Solution: X_L = 5 Ω, X_C = 10 Ω, R = 10 Ω.
- A.10√2 Ω
- B.15 Ω
- C.5√5 Ω✓
- D.15√2 Ω
Correct Answer
(C) 5√5 Ω
Solution & Explanation
Answer: (C) 5√5 Ω Solution: X_L = 5 Ω, X_C = 10 Ω, R = 10 Ω. Z = √((X_C − X_L)² + R²) = √((10 − 5)² + 10²) = √(25 + 100) = √125 = 5√5 Ω.

PhysIf Z₁ and Z₂ are the impedances of the given circuits (a) and (b) as shown in figures, then choose the correct option.PhysA 100 Ω resistance and a capacitor of 100 Ω reactance are connected in series across a 220 V source. When the capacitor is 50% charged, the peak value of the displacement current isPhysAn electric dipole with dipole moment 5 × 10⁻⁶ C·m is aligned with the direction of a uniform electric field of magnitude 4 × 10⁵ N/C. The dipole is then rotated through an angle of 60° with respect to the electric field. The change in the potential energy of the dipole is:PhysTwo identical charged conducting spheres A and B have their centres separated by a certain distance. Charge on each sphere is q and the force of repulsion between them is F. A third identical uncharged conducting sphere is brought in contact with sphere A first and then with B and finally removed from both. New force of repulsion between spheres A and B (radii negligible vs separation, treated as point charges) is best given as:PhysThe plates of a parallel plate capacitor are separated by d. Two slabs of different dielectric constant K1 and K2 with thickness 3d/8 and d/2 respectively are inserted in the capacitor. Due to this, the capacitance becomes two times larger than when there is nothing between the plates. If K1/K2 = 1.25, the value of K1 is:PhysA sphere of radius R is carved out of a uniform solid sphere of radius 2R (internally tangent, so its centre is at distance R from the big centre). The ratio of the moment of inertia of the small sphere to that of the remaining part, both about the Y-axis through the big sphere's centre, is:PhysThe Sun rotates once in 27 days. If it expanded to twice its present radius (uniform-density sphere, no external influence), its new period would be about:PhysA uniform rod of mass 20 kg and length 5 m leans against a smooth vertical wall, making 60° with the wall; its lower end rests on a rough horizontal floor. The friction force exerted by the floor is: (g = 10 m/s²)
