A 4µF conductor is charged to 400 volts and then its plates are joined through a resistance of 1 kΩ. The heat produced in the resistance is
-
- 0.16 J
- 1.28 J
- 0.64 J
- 0.32 J
Correct Option: D
| The energy stored in the capacitor = | CV² | |
| 2 |
| = | × 4 × 10-6 × (400)² | |
| 2 |
= 0.325
This energy will be converted into heat in the resistor
