A) A will decrease, V will increase
B) A will increase, V will decrease
C) both A and V will increase
D) both A and V will increase
Correct Answer: B
Solution :
When a resistance is joined in parallel with voltmeter. Now V and S are in parallel so it become an ammeter. \[\therefore \]A and\[{{A}_{1}}\] the two ammeters are in series reading will become equal. \[\therefore \]A increases and in parallel R decreases which decreases V.You need to login to perform this action.
