| The actual value of resistance R, shown in the figure is \[30\Omega \] This is measured in an experiment as shown using the standard formula\[R=\frac{V}{1},\] where V and I are the readings of the voltmeter and ammeter, respectively. |
 |
| If the measured value of R is \[5%\] less, then the internal resistance of the voltmeter is: |
A) \[600\Omega \]
B) \[570\Omega \]
C) \[35\Omega \]
D) \[350\Omega \]
Correct Answer: B
Solution :
\[\frac{30R}{R+30}=30\times 00.95\]\[\Rightarrow \] \[R=570\Omega .\]
