A (30\text{ V}\) source supplies a circuit consisting of a resistor \(R_{1}=5\ \Omega\) in series with a parallel combination of two resistors \(R_{2}\) and \(R_{3}\). The total current drawn from the source is \(3\ \text{A}\). The current through \(R_{2}\) exceeds the current through \(R_{3}\) by \(0.5\ \text{A}\). Determine the resistance values of \(R_{2}\) and \(R_{3}\) (in ohms).

Answer Options

A. R2 = 12 Ω, R3 = 60/7 Ω (≈8.57 Ω)
B. R2 = 15 Ω, R3 = 10 Ω
Correct Answer C. R2 = 60/7 Ω (≈8.57 Ω), R3 = 12 Ω
D. R2 = 30/5 Ω (≈6 Ω), R3 = 9 Ω
Correct Answer
C
Correct Option:
R2 = 60/7 Ω (≈8.57 Ω), R3 = 12 Ω
