Capacitors of 2 μF and 3 μF are joined in series. What is the equivalent capacitance?
Answer and explanation
Correct answer: D. 1.2 μF
- Step 1: For series capacitors , so μF. Answer: 1.2 μF. Why not the others: 5 μF: adds the capacitances, which is the parallel rule. 2.5 μF: takes the average. 6 μF: multiplies without dividing.
