For the reading obtained in ideal voltmeters and ammeters in above circuits.

Options

A. `V_2 gt V_1` and `i_1 gt i_2`
B. `V_2 lt V_1` and `i_1=i_2`
C. `V_1=V_2` and `i_1 gt i_2`
D. `V_1=V_2` and `i_1 = i_2`

Answer

D

Explanation

Current in circuit (1) ,

`i_1=V/R=10/10`=1A
Current in circuit (2),

For the ideal voltmeter, there will not be any effect of resistance connected in series with it.
Hence `i_2=10/10`=1 A
`V_1=10 i_1 = 10 xx1`=10 Volt
`V_2=10 i_2 = 10 xx1` = 10 Volt
`therefore V_1=V_2` and `i_1=i_2`
