Question 664: Current Electricity

Question

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

Accepted Answer

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 V
B
= V
C
,
$$ 	herefore $$  V
A
= V
B
= V
C

Answer

VA  =  VB  $$ 
e $$  VC

Answer

VA  $$ 
e $$  VB  $$ 
e $$  VC

Answer

VA  =  VB  =  VC

Answer

VA  $$ 
e $$  VB  =  VC
