The value of current I in the given circuit is (a) 7 A (b) 8 A (c) 18 A (d) 10 A

Answer: (c). Top-left corner: 20 A in, 15 A down, so 5 A goes right. Top-right corner: 5 + 3 = 8 A goes down. Bottom-left corner: 15 A in, 5 A out, so 10 A goes right. Bottom-right corner: I = 10 + 8 = 18 A So the answer is (c) 18 A.

The value of current I in the given circuit is

Show answer and solution

Answer: (c)

Top-left corner: $20$ A in, $15$ A down, so $5$ A goes right.
Top-right corner: $5 + 3 = 8$ A goes down.
Bottom-left corner: $15$ A in, $5$ A out, so $10$ A goes right.
Bottom-right corner: $I = 10 + 8 = 18$ A
So the answer is (c) 18 A.
