Moving Coil Galvanometer, Ammeter & Voltmeter

When a resistance of $100\ \Omega$ is connected in series with galvanometer of resistance $R$ , its range is $V$ . To double its range, another additional resistance of $1000\ \Omega$ is connected in series. Find the value of $R$ .

Show answer and solution

Answer: (c)

Range $V = I_g(R + R_{series})$ .
$V = I_g(R + 100)$ and $2V = I_g(R + 100 + 1000)$
$2(R + 100) = R + 1100 \Rightarrow R = 900\ \Omega$
So the answer is (c) $900\ \Omega$ .
