A) 0.75 A
B) 1 A
C) 2 A
D) 1.5 A
Correct Answer: B
Solution :
Required arrangement is shown in figure. The equivalent circuit will look like (since the two resistances of \[1\,\Omega \] and \[2\,\Omega \]. are in series, which form \[3\,\Omega \] which is in parallel with \[3\,\Omega \]. resistance). Therefore, the effective resistance is \[\frac{(1+2)\times 3}{(1+2)+3}=\frac{3}{2}\,\Omega \] \[\therefore \] Current in the circuit, \[I=\frac{3}{(3/2)}=2\,A\] \[\therefore \] Current in \[3\,\,\Omega \] resistor \[=\frac{I}{2}=1\,\,A\]You need to login to perform this action.
