A) \[2.3\,\,A\]
B) \[4.0\,\,A\]
C) \[2.0\,\,A\]
D) \[1.33\,\,A\]
Correct Answer: C
Solution :
Using the relation for current \[i=\frac{E}{R+r}\] ? (1) But the equivalent resistance in the upper arm is given by as \[{{R}_{equivalent}}=4\Omega +\frac{2\times 3}{2+3}\Omega \] \[{{R}_{q}}=4+\frac{6}{5}=\frac{26}{5}=5.2\] Now equation (1) we get \[i=\frac{12}{5.2+0.8}=\frac{12}{6}=2\,\,amp\]You need to login to perform this action.
