In the two circuits shown (same 10 V cell, same 10 $Ω$ resistor; ideal meters, only the order of V and A swapped), the readings of the voltmeters and ammeters will be:

Answer: (C) V $_{1}$ = V $_{2}$ and i $_{1}$ = i $_{2}$ . \textbf{Answer:} (3) V $_{1}$ = V $_{2}$ and i $_{1}$ = i $_{2}$ \textbf{Solution:} Ideal ammeter (0 $Ω$ ) and voltmeter (∞ $Ω$ ): swapping their order doesn't change the circuit.

NEET 2019 Physics question — In the two circuits shown (same 10 V cell, same 10 resistor; ideal meters, only the order…

A.V $_{2}$ > V $_{1}$ and i $_{1}$ > i $_{2}$
B.V $_{1}$ = V $_{2}$ and i $_{1}$ > i $_{2}$
C.V $_{1}$ = V $_{2}$ and i $_{1}$ = i $_{2}$ ✓
D.V $_{2}$ > V $_{1}$ and i $_{1}$ = i $_{2}$

Correct Answer

Solution & Explanation

\textbf{Answer:} (3) V $_{1}$ = V $_{2}$ and i $_{1}$ = i $_{2}$ \textbf{Solution:} Ideal ammeter (0 $Ω$ ) and voltmeter (∞ $Ω$ ): swapping their order doesn't change the circuit. V = 10 V across 10 $Ω$ , i = 1 A in both $\Rightarrow$ equal readings.

PhysA constant voltage of 50 V is maintained between points A and B of the circuit shown. The current through the branch CD of the circuit is:PhysThe current passing through the battery in the given circuit is:PhysThe magnitude and direction of the current in the following circuit is:PhysThe potential difference (V_A - V_B) between points A and B in the figure (current 2 A from A to B through 2 , a 3 V cell, then 1 ) 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:
