A) \[115\mu A\]
B) \[170\mu A\]
C) \[60\mu A\]
D) \[150\mu A\]
Correct Answer: B
Solution :
Since it is a balanced wheat stone bridge, its equivalent resistance =\[=\frac{4}{3}\Omega \] \[\varepsilon =B\ell \text{v}=5\times {{10}^{-4}}V\] So total resistance \[R=\frac{4}{3}+1.7\approx 3\Omega \] \[\therefore \]\[i=\frac{\varepsilon }{R}\approx 166\mu A\approx 170\mu A\]You need to login to perform this action.
