Three capacitors — C1 = 10 µF, C2 = 10 µF, and C3 = 10 µF — are connected in parallel. What is the total capacitance?

  1. A. 3.33 µF
  2. B. 10 µF
  3. C. 20 µF
  4. ✓ 30 µFCorrect

Why D is correct

Capacitors in parallel add directly: Ct = C1 + C2 + C3 = 10 + 10 + 10 = 30 µF. This is the opposite of resistors; the reciprocal rule applies to capacitors in series, not in parallel. (NEETS Mod. 2 §3-2)
