NEET 2024 · PhysicsPower splitPrevious Year Question

Two heaters A and B rated 1 kW and 2 kW are connected first in series and then in parallel to a fixed source. The ratio of power outputs (series : parallel) is:

Answer: (A) 2 : 9. \textbf{Answer:} (1) 2 : 9 \textbf{Solution:} R 1/P.

  1. A.2 : 9
  2. B.1 : 2
  3. C.2 : 3
  4. D.1 : 1

Correct Answer

(A) 2 : 9

Solution & Explanation

\textbf{Answer:} (1) 2 : 9 \textbf{Solution:} R 1/P. Series P_s = V/(R+R) = 2/3 (in units of V). Parallel P_p = 3. Ratio = (2/3)/3 = 2 : 9.

PhysTwo resistors 100 and 200 are connected in parallel. The ratio of thermal energy developed in 100 to that in 200 in a given time is:PhysThree resistors r1, r2, r3 are connected as shown. The ratio i3/i1 of currents in terms of the resistances is:PhysSix similar bulbs are connected as shown with a DC source of emf E and zero internal resistance. The ratio of power consumed when (i) all glow to (ii) when two of section A and one of section B glow, is:PhysAn 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:
