The current in the following circuit is (a) 2/3 A (b) 1 A (c) 1/8 A (d) 2/9 A

Answer: (b). Across two corners of the triangle: one 3 Ω is in parallel with 3 + 3 = 6 Ω. Req = (3 × 6)/(9) = 2 Ω I = 2/2 = 1 A So the answer is (b) 1 A.

The current in the following circuit is

Show answer and solution

Answer: (b)

Across two corners of the triangle: one $3\ \Omega$ is in parallel with $3 + 3 = 6\ \Omega$ .
$R_{eq} = \frac{3 \times 6}{9} = 2\ \Omega$
$I = \frac{2}{2} = 1$ A
So the answer is (b) $1$ A.
