Question:

The current in resistance R₃ in the given circuit is

Options:

1 A

2/3 A

0.25 A

0.50 A

Correct Answer:

2/3 A

Explanation:

Current through $R_1$ and $R_2$ comes out to be zero (potential difference = 0)

∴ Current through, $R_3=\frac{\text { Net emf }}{\text { Total resistance }}=\frac{(4+3+2)-(2+3+2)}{3}=\frac{2}{3} A$
