Question

The current i in this circuit section shown is .

• A. 1 A
• B. 2 A
• C. 3 A
• D. 0 A

Answer 1

The correct option is D 0 A

Kirchoff’s junction law says that the algebraic sum of currents flowing into a junction is zero.
That’s just a fancy way of saying that total current going into the junction is equal to the total current coming out of it.
So, 2+3+5 = 6+4+i
$\Rightarrow$ i=0 A
