Physics · Capacitance
A 10 μF capacitor is fully charged to a potential difference of 50 V. After removing the source voltage, it is connected to an uncharged capacitor in parallel. Now the potential difference across them becomes 20 V. The capacitance of the second capacitor is:
- 130 μF
- 215 μF✓
- 310 μF
- 420 μF
Correct answer
15 μF
