Physics · Electrostatic Potential and Capacitance
A capacitor of capacitance C = 900 pF is charged fully by a 100 V battery. Then it is disconnected from the battery and connected in parallel to another uncharged capacitor of capacitance C = 900 pF. The total electrostatic energy stored by the system after connection is:
- 11.50 × 10-6 J
- 24.50 × 10-6 J
- 33.25 × 10-6 J
- 42.25 × 10-6 J✓
Correct answer
2.25 × 10-6 J
