Question
Three voltmeters, all having different resistances, are joined as shown. When some potential difference is applied across A and B, their readings are V1, V2, V3 :
Options
A.V1 = V2
B.V1 ≠ V2
C.V1 + V2 = V3
D.V1 + V2 > V3
Solution
In parallel combination potential difference are same
So V1 + V2 = V3
Here V1 and V2 are in series but their resistances are different
So V1 = iR1
V2 = iR1
V1 ≠ V2
So V1 + V2 = V3
Here V1 and V2 are in series but their resistances are different
So V1 = iR1
V2 = iR1
V1 ≠ V2
