Q.35. In order to convert a milliammeter of range 1.0 mA and resistance 1.0 ohm into a voltmeter of range 10 V, a resistance of how many ohms should be connected with it and in what manner?

Open in App

Solution

Dear student,
$I_{s} = \frac{V}{R + R_{m}} o r R = \frac{V}{I_{s}} - R_{m} R = \frac{10}{1 \times 10^{- 3}} - 1 R = 10000 - 1 R = 9999 o h m s$
