Three capacitors each of capacity 4 μF are to be connected in such a way that the effective capacitance is 6 μF. This can be done by
- connecting two in parallel and one in series
- connecting all of them in series
- connecting them in parallel
- connecting two in series and one in parallel
Correct answer: connecting two in parallel and one in series
Solution
To achieve an effective capacitance of 6 μF, two capacitors (4 μF each) are connected in parallel, giving an equivalent capacitance of 8 μF. This combination is then connected in series with the third capacitor (4 μF), resulting in an effective capacitance of 6 μF.
