A potential of `400 V` is applied at the point `A`. The value of resistance `R_(1)=1000 Omega`, `R_(2)=2000Omega` and `R_(3)=1000Omega` are connected between points `A` and `G` as shown in the figure. Point `G` is earthed. The measured potential difference by an ideal voltmeter connected across `R_(2)` is

A

`100 V`

B

`200 V`

C

`300 V`

D

`400 V`

Text Solution

Verified by Experts
