The value of current J in the circuit will be

A)  1.7 A                                    

B)  2.1 A                    

C)  3 A                        

D)         zero

Correct Answer: A

Solution :

According to Kirchhoffs junction rule, Sum of incoming currents                 = Sum of outgoing currents                 \[2+2=1+1.3+I\] \[\therefore \]  \[I=1.7\,\,A\]
