The correct answer is (c) 0.54 A
To explain: In the given figure, RX = RY = RZ = \(\frac{5×5}{5+5+5}\) = 1.67 Ω
Here, R = [(RX + 2) || (RY + 3)] + RX
= (3.67 || 4.67) + RZ
= \(\frac{3.67 × 4.67}{3.67 + 4.67}\) + 1.67
= \(\frac{17.1389}{8.34}\) + 1.67
= 3.725 Ω
∴ I = \(\frac{V}{R} = \frac{2}{3.725}\) = 0.54 A.
