Two capacitor problem (open circuit version)
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?

1000V, since voltage across discharged cap is 0V.
