Three voltmeters, all having different internal resistance are joined as shown in figure when some potential difference is applied across A and B, their reading are V 1 , V 2 and V 3 . choose the correct option. V 1 V 2 V 3

1. V 1 + V 2 > V 3
2. V 1 = V 2
3. V 1 ≠ V 3 – V 2
4. V 1 + V 2 = V 3

Correct answer: V 1 + V 2 = V 3
