The value of current \[I\] in the circuit will be

A) 1.7 A     

B)  2.1 A

C)  3 A                                        

D)  zero

Correct Answer: A

Solution :

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