An ammeter `A` of finite resistance, and a resistor `R` are joined in series to an ideal cell `C`. A potentiometer `P` is joined in parallel to `R`. The ammeter reading is `I_(0)` and the potentiometer reading is `V_(0)`. `P` is now replaced by a voltmeter of finite resistance. The ammeter reading now is `I` and the voltmeter reading is `V`.

A

`I gt I_(0),V gt V_(0)`

B

`I gt I_(0),V lt V_(0)`

C

`I = I_(0),V lt V_(0)`

D

`I lt I_(0), V = V_(0)`
