Current Electricity question

2015 · Q118

NEETPhysicsCurrent ElectricityMCQ+4 / −1
A, B and C are voltmeters of resistance R, 1.5 R and 3R respectively as shown in the figure. When some potential difference is applied between X and Y, the voltmeter readings are VA, VB and VC respectively, Then

    VA = VB ≠\ne= VC
  2. B
    VA ≠\ne= VB ≠\ne= VC
  3. C
    VA = VB = VC
  4. D
    VA ≠\ne= VB = VC
View written solutionFree

Correct answer: C

Effective resistance of
B & C = (1.5R)(3R)/(1.5R + 3R) = R

In series sequence voltage across A = voltage across B & C

Now B & C are parallel, so VB = VC,

∴\therefore∴ VA = VB = VC
