| Meshka7:
What happens when you charge a capacitor to a 1000V then connect another discharged capacitor to the 1000V terminal (without completing the circuit)? What will be the potential on both sides of the discharged capacitor? will it get charged? |
| Yansi:
No, why should it? The circuit is incomplete. |
| Shock:
Best to draw out the schematic in both states and mark where your measurement is across. Also you can test this with two low voltage capacitors or a circuit simulator it's a lot safer, unless you are talking about dielectric absorption or something else to do with a high voltage capacitor. |
| Meshka7:
No, it's a theoretical question. Not planning to try it out. floating A------|1000V|----------|Discharged|----------floating B The question is: What is the voltage at point B? |
