Question

five identical capacitors connected in series have equivalent capacitance of 4 microfarad if all of them are now connected in parallel across 400 volt source energy stored in them will be​

Answer 1

Explanation:

Suppose C µF is the capacitance of each capacitor. Since 5 (= n) capacitors are connected in series, c/n =4 or C = 4 n = 4 × 5 = 20 µF When the capacitors are connected in parallel, then equivalent capacitance C′
