The magnitude and direction of the current in the circuit shown will be

A)  7/3 A from a to b through e

B)  7/3 A from b to a through e

C)  1 A from b to a through e

D)  1 A from a to b through e

Correct Answer: D

Solution :

Since \[{{E}_{1}}\] \[(10V)>{{E}_{2}}(4V)\] So, current in the circuit will be clockwise, Applying Kirchhoffs voltage law \[-1\times i-10-4\times -2\times i-3i=0\] \[i=1A\]                     (a fob via e) Current \[=\frac{V}{R}=\frac{10-4}{6}=1A\]
