Kirchhoff's Laws & Measuring Instruments

The range of voltmeter of resistance ' GG ' Ω\Omega is ' VV ' volt. The resistance required to be connected in series with it in order to convert it into a voltmeter of range ' nVnV ' volt, will be

Show answer and solution

Answer: (a)

  1. Full-scale current Ig=VGI_g = \frac{V}{G}.
  2. For range nVnV: Ig(G+R)=nV⇒G+R=nGI_g(G + R) = nV \Rightarrow G + R = nG
  3. R=(n−1)GR = (n - 1)G, so the answer is (a).
