# Capacitance

### Explanation of question 10

Two identical electrolytic capacitors, each marked 50mF, 400V, are connected in series. A single equivalent electrolytic capacitor will be marked

1. 100 mfd, 800V
2. 100 mfd, 200V
3. 25 mfd, 800V
4. 25 mfd, 200V

The answer is :- 3 Equivalent capacitance of series combination = 25mF. 400 V across each capacitor is equivalent to 800 V across a single equivalent capacitor.
