When two identical capacitors are in series, they have 3 μF capacitance

When two identical capacitors are in series, they have 3 μF capacitance and when in parallel 12 μF. What is the capacitance of each?

Options

(a) 6 μF
(b) 3 μF
(c) 12 μF
(d) 9 μF

Correct Answer:

6 μF

Explanation:

Let C = each capacitance

In parallel, (C + C) = 12 ⇒ 2C = 12

⇒ C = 6 μF
