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

Options

A. `V_(2) gt V_(1) and i_(1)=i_(2)`
B. `V_(1)=V_(2) and i_(1) gt i_(2)`
C. `v_(1)=V_(2) and i_(1)=i_(2)`
D. `V_(2) gt V_(1) and i_(1) gt i_(2)`

Answer

C

Explanation

In case of ideal voltmeter, resistance is infinite and for the ideal ammeter, resistance is zero.
`V_(1)=i_(1)xx 10=(10v)/(10Omega)xx 10=10" volt " :.i_(1)=(V)/(R )`
`V_(2)=i_(2)xx10=(10)/(10) xx 10=10` volt
`V_(1)=V_(2)`
`i_(1)=i_(2)=(10V)/(10Omega)=1A`
