NEET Physics Conversion of Instruments MCQ Question with Solution

The range of voltmeter of resistance 300 $\Omega$ is 5 V. The resistance to be connected to convert it into an ammeter of range 5 Å is

A

1 $\Omega$ in series

B

1 $\Omega$ in parallel

C

0.1 $\Omega$ in series

D

0.1 $\Omega$ in parallel

Correct Answer

Option D

Detailed Explanation

To convert a voltmeter to an ammeter, a shunt resistance is used. The shunt resistance $R_s = \frac{V}{I} - R_v = \frac{5}{5} - 300 = 0.1 \Omega$ in parallel.
