A) \[0.36\,ampere\]
B) \[0.50\,ampere\]
C) \[2.0\,ampere\]
D) \[4.5\,ampere\]
Correct Answer: B
Solution :
The ammeter records the total current supplied by the battery of equivalent emf \[4V\] to a circuit, of equivalent resistance\[8\Omega \], (Resistance of \[2\Omega \] and \[2\Omega \] are in parallel, their resultant is in series with resistors of \[2\Omega ,\,\,3\Omega \] and the two internal resistances of\[1\Omega \]) So, \[I=\frac{V}{R}=\frac{4}{8}\mathbf{=0}\mathbf{.5}\,\,\mathbf{Amp}\]
