`A, B` and `C` are voltmeters of resistances `R, 1.5R` and `3R` respectively. When some potential difference is applied between `x` and `y` the voltmeter readings are `V_A, V`_B`and `V_C,` then

A

`V_A=V_B=V_C`

B

`V_A!=V_B=V_C`

C

`V_A=V_B -= V_C`

D

`V_A+V_B=V_C`

Text Solution

Verified by Experts

The correct Answer is:
A
`B` and `C` are in parallel
`:. V_B=V_C`
Further `R_A=R`
`R_(BC)=((1.5R)(3R))/(1.5R+3R)=R`
or `R_A=R_(BC)`
`:. V_A=V_(BC)`
because `iR_A=iR_(BC)`
