Suppose that AV - 18 V Express your answer as an integer and include the appropriate units. Enter the positive value if the current is directed to the right and the negative value if current is directed to the left. I- Value Units gure 1 of 1 Submit AV Provide Feedback Next> 2 S2 5(2 ISV

Explanation / Answer

current through 2 ohm = 18/2 = 9 A

current through 5 ohms = 15/5 = 3 A

now Apply kirchoff's junction law

In = Iout

9 = 3 + I

==> I = 9 - 3

= 6 A <<<<<<<-------Answer
