An ammeter and a voltmeter are joined in sereis to a cell. Their readings are `A` and `V` respectively. If a resistance is now joinding parallel with the voltmeter. Then

Options

A. both A and V will increase
B. both A and V will decreases
C. A will decreases, V will increases
D. A will increases, V will decreases

Answer

D

Explanation

Equivalent resistance so current will increases.
`V_(A)+V_(V)=V`
Due to change `V_(A)` increases so voltmeter reading will decrease.
