In the circuits shown below, the readings of the voltmeters and the ammeters will be:

Options

A. `V_(2)gtV_(1)` and `i_(1)gti_(2)`
B. `V_(2)gtV_(1)` and `i_(1)=i_(2)`
C. `V_(1)=V_(2)` and `i_(1)gti_(2)`
D. `V_(1)=V_(2)` and `i_(1)=i_(2)`

Answer

D

Explanation

Resistance for ideal voltemeter `=infty`
Resistance for ideal ammeter =0
`(1)/(R_(eq))=(1)/(R_(1))+(1)/(R_(2))`
`(1)/(R_(eq))=(1)/(10)+(1)/(infty)`
`(1)/(R_(eq))=(1)/(10)+0`
`R_(eq)=10 Omega`
`i_(1)=(V)/(R)=(10)/(10)=1A`
`v_(1)=10V`
In `II^(nd)` circuit
`(1)/(R_(eq))=(1)/(R_(1))+(1)/(R_(2))`
`(1)/(R_(eq))=(1)/(10)+(1)/(10+infty)`
`(1)/(R_(eq))=(1)/(10)+0`
`R_(eq)=10 Omega`
`i_(2)=(1-0)/(10)=1A`
`v_(2)=10V`
