Solution

The correct option is C $V_{1} + V_{2} = V_{3}$
Potential difference occurs P and Q $=$ Potential difference across $V_{1}$ and $V_{2} =$ Potential difference $V_{3}$
i.e, $V_{1} + V_{2} = V_{3}$
Since the current will be thesame through $V_{1}$ and $V_{2}$ and equivalently in $V_{3}$

Three voltmeters A, B and C having resistances R, 1.5R and 3R, respectively are used in a circuit as shown when a potential difference is applied between X and Y, the reading of the voltmeters are $V_{1}, V_{2}$ and $V_{3}$ respectively then:

Q. For three circuits, shown here

the same two resistors R₁ and R₂ have been connected in parallel in all the circuits but the voltmeter and the ammeter have been connected in three different positions. The relation between the three voltmeter and ammeter readings would be :

Three voltmeters, all having different resistances, are joined as shown in the fig. When some potential difference is applied difference is applied across A and B, their reading are V1,V2,V3:

The correct option is C V1+V2=V3Potential difference occurs P and Q = Potential difference across V1 and V2= Potential difference V3i.e, V1+V2=V3Since the current will be thesame through V1 and V2 and equivalently in V3
