A) \[30\mu A\]
B) \[90\mu A\]
C) \[4mA\]
D) \[2mA\]
Correct Answer: B
Solution :
Here, the resistances \[400\Omega \]and \[10000\Omega \]. are in parallel, their effective resistance \[{{R}_{P}}\] will be \[{{R}_{P}}=\frac{400\times 10000}{400+10000}\] \[=\frac{5000}{13}\Omega \] Total resistance of the circuit \[=\frac{5000}{13}+800=\frac{15400}{13}\Omega \] Current in the circuit, \[l=\frac{6}{15400/13}=\frac{37}{7700}A\] Potential difference across voltmeter \[=l{{R}_{P}}=\frac{39}{7700}\times \frac{5000}{13}=1.95V\]You need to login to perform this action.
