In the circuit, R_B and R_C are in series. The equivalent resistance of the circuit is:

1. 12 Ω
2. 6 Ω
3. 3 Ω
4. 15 Ω

Correct answer: 12 Ω

Solution

When resistors R_B and R_C are in series, their equivalent resistance is the sum of their individual resistances. Without specific values for R_B and R_C, the question seems incomplete, but assuming the correct answer is 12 Ω, the resistors likely add up to this value.
