A) \[0.03\,\Omega \]
B) \[0.3\,\Omega \]
C) \[0.9\,\Omega \]
D) \[0.09\,\Omega \]
Correct Answer: D
Solution :
To increase the range of ammeter we have to connect a small resistance in parallel (shunt), let its value be\[R.\] Apply KCL at junction to divide the current. Voltage across \[R=\]Voltage across ammeter \[\Rightarrow \] \[9R=0.81\times 1\] \[\Rightarrow \] \[R=\frac{0.81}{9}=0.09\Omega \]You need to login to perform this action.
