In the circuit shown in figure reading of voltmeter is `V_(1)` when only `S_(1)` is closed, reading of voltmeter is `V_(2)` when only `S_(2)` is closed and reading of voltmeter is `V_(3)` when both `S_(1)` and `S_(2)` are closed. Then

A

`v_3gt v_2 gt v_1`

B

`v_2gt v_1 gt v_3`

C

`v_3 gt v_1 gt v_2`

D

`v_1 gt v_2 gt v_3`

Text Solution

Verified by Experts

`V_1=E/(R+3R)=3/4E=0.75E, V_2=E/(R+6R)=6/7E=0.86E`
`V_3=E/(R+2R).2R=2/3E=0.66E, V_2 gt V_1 gt V_3`
