Solution

The correct option is A
1A, 0.5A

Potential difference between points a and b = 30-20 = 10V, hence current through 10ohm resistor $= \frac{V}{R} = \frac{10}{10} = 1 A$
Similarly, potential difference between points b and c = 20-10 = 10V.
Current through 20ohm resistor $= \frac{V}{R} = \frac{10}{20} = 0.5 A$
