Question
Three voltmeters are connected in a circuit as shown in diagram. Find correct relation among their readings (V1, V2and V3).
Options :
V1 > V2 = V3
V1 + V2 = V3
V1 = V2 + V3
V1 + V3 = V2
Answer :
V1 + V2 = V3
Solution :
Across points P & Q (V1 & V2) combined is in parallel to (V3)
Therefore V12 = V3 ⇒ V1 + V2 = V3
