In the circuit shown, a 12 V ideal battery has an internal resistance of \(0.5\ \Omega\). It is connected in series with a resistor \(R_{1}=2\ \Omega\), after which the circuit splits into two parallel branches: one containing a resistor \(R_{2}=3\ \Omega\) and the other a resistor \(R_{3}=6\ \Omega\). The branches recombine and return to the battery. Determine (i) the current supplied by the battery, (ii) the potential difference across \(R_{2}\), and (iii) the power dissipated in \(R_{3}\).

Answer Options

Correct Answer A. I = 8/3 A, V_R2 = 16/3 V, P_R3 = 128/27 W
B. I = 2 A, V_R2 = 6 V, P_R3 = 24 W
C. I = 3 A, V_R2 = 9 V, P_R3 = 54 W
D. I = 8\/3 A, V_R2 = 8 V, P_R3 = 128\/3 W
Correct Answer
A
Correct Option:
I = 8/3 A, V_R2 = 16/3 V, P_R3 = 128/27 W
