| An intriguing Consideration: |
|
| |
| A capacitor is charged to 10V, and is connected to another of the same value with a switch. When the switch is closed, the voltage on both capacitors becomes 5V, which meets the law of conservation of charge, Q=CV. But when the before and after energies are calculated according to E=1/2 CV² , half of the energy appears to disappear. This is true because the capacitance doubles, but the voltage halves. Hmmm. How? |
