ગેલ્વેનોમીટર આવર્તન (વિચલન) બતાવતું નથી. રીએક્ટન્સ $x$ ....................... $\Omega$ છે ?

A

$6$

B

$3$

C

$12$

D

આપેલ પૈકી એકપણ નહિ

Solution

$G = 0$ સ્થિતિમાં

$\frac{{{R_1}}}{{{R_2}}}\,\, = \,\,\frac{{{R_3}}}{{{R_4}}}\,\,\,\,\,\, \Rightarrow \,\,\,\frac{{6x}}{{(6 + x)}}\,\,\, = \,\,\,\,\frac{6}{3}$

$\therefore \,\,\,x\,\, = \,\,12\,\,\Omega $.
