A) 99995
B) 9995
C) \[{{10}^{3}}\]
D) \[{{10}^{5}}\]
E) None of these
Correct Answer: B
Solution :
Voltage sensitivity \[=\frac{\text{Current sensitivity}}{\text{Resistance}\,\text{of}\,\text{galvanometer}\,\,\text{G}}\] \[\Rightarrow \] \[G=\frac{10}{2}=5\,\Omega \] Here, \[{{I}_{g}}=\]Full scale deflection current \[=\frac{150}{10}=15\,mA\] V = voltage to be measured\[=150\times 1=150\,V\] Hence, \[R=\frac{V}{{{I}_{g}}}-G\] \[=\frac{150}{15\times {{10}^{-3}}}-5\] \[=9995\,\Omega \]You need to login to perform this action.
