A

Both A and V will increase

B

Both A and V will decrease

C

A will decrease and V will increase

D

A will increase and V will decrease

Text Solution

Verified by Experts

The correct Answer is:
D
R in parallel with voltmeter decreases the resistance there for current will increase in the circuit.
