Capacitors in series and parallel combine differently:
- Series: \( \frac{1}{C_{eq}} = \frac{1}{C_1} + \frac{1}{C_2} + \dots \)
- Parallel: \( C_{eq} = C_1 + C_2 + \dots \)
Step 1: Combine 12 mF and 4 mF in series
\[ \frac{1}{C_1} = \frac{1}{12} + \frac{1}{4} = \frac{1 + 3}{12} = \frac{4}{12} \Rightarrow C_1 = \frac{12}{4} = 3 \, \text{mF} \]
Step 2: Combine result with 9 mF in parallel
\[ C_2 = 3 + 9 = 12 \, \text{mF} \]
Step 3: Combine C2 with 6 mF in series
\[ \frac{1}{C_{eq}} = \frac{1}{6} + \frac{1}{12} = \frac{2 + 1}{12} = \frac{3}{12} \Rightarrow C_{eq} = \frac{12}{3} = 4 \, \text{mF} \]
