In the circuits shown below, the readings of the voltmeters and the ammeters will be:           [NEET 2019]

A)  \[{{V}_{1}}={{V}_{2}}\text{ }and\text{ }{{i}_{1}}={{i}_{2}}\]

B)  \[{{V}_{2}}>{{V}_{1}}\text{ }and\text{ }{{i}_{1}}>{{i}_{2}}\]

C)  \[{{V}_{2}}>{{V}_{1}}\text{ }and\text{ }{{i}_{1}}={{i}_{2}}\]

D)  \[{{V}_{1}}={{V}_{2}}\text{ }and\text{ }{{i}_{1}}>{{i}_{2}}\]

Correct Answer: A

Solution :

[a]

\[{{i}_{1}}=\frac{10V}{10\Omega }=1A\]     \[{{R}_{{{v}_{2}}}}=\infty \]

\[{{V}_{1}}=10V\]                  \[{{i}_{through\,volumeter}}=0\]

\[{{V}_{2}}=10V\]

\[{{i}_{2}}=1A\]

\[{{V}_{1}}={{V}_{2}}\] \[{{i}_{1}}={{i}_{2}}\]
