Question

A voltmeter has resistance of G ohm and range of V volt.The resistance required in series to convert it into a voltmeter of range n V volt is (A)  (n - 1) G  (B)  nG  (C)  (G/n)  (D)  (G/(n - 1))

Resistance required in series is R = (V/Ig) - G = (nV/((V)G )) - G = (n - 1) G

Q. A voltmeter has resistance of G ohm and range of V volt.The resistance required in series to convert it into a voltmeter of range n V volt is

$(n - 1) G$

$n G$

$\frac{G}{n}$

$\frac{G}{( n - 1 )}$

Resistance required in series is
$R = \frac{V}{I _{g}} - G = \frac{nV}{( \frac{V}{G} )} - G = (n - 1) G$

Q. A voltmeter has resistance of G ohm and range of V volt.The resistance required in series to convert it into a voltmeter of range n V volt is

(n−1)G

nG

nG​

(n−1)G​

Resistance required in series is R=Ig​V​−G=(GV​)nV​−G=(n−1)G

$(n - 1) G$

$n G$

$\frac{G}{n}$

$\frac{G}{( n - 1 )}$

Resistance required in series is
$R = \frac{V}{I _{g}} - G = \frac{nV}{( \frac{V}{G} )} - G = (n - 1) G$
