Connecting a conductor with a voltage source

Click For Summary
SUMMARY

The discussion centers on the behavior of a capacitor when the distance between its plates is doubled while a 100 V voltage source is applied. Despite the introduction of the voltage source, the voltage across the capacitor plates remains at 200 V. This phenomenon occurs because the voltage source compensates for the work done in moving the plates apart, maintaining the voltage constant up to a certain limit. The explanation highlights the interplay between electric fields and voltage sources in capacitive systems.

PREREQUISITES
  • Understanding of capacitor fundamentals, including voltage and electric fields.
  • Familiarity with the concept of voltage sources and their impact on circuits.
  • Knowledge of basic physics principles related to work and energy in electrical systems.
  • Concept of current flow in response to voltage changes in capacitive circuits.
NEXT STEPS
  • Study the relationship between capacitance, voltage, and distance in capacitors.
  • Learn about the effects of voltage sources on capacitive circuits.
  • Explore the concept of electric field strength and its relation to voltage in capacitors.
  • Investigate the principles of energy conservation in electrical systems involving capacitors.
USEFUL FOR

This kind of confuses me. You have a capacitor which has a voltage of 200 volts. Now when doubling the distance between the plates and adding a 100 V voltage source to it, it is said that the voltage between the capacitor plates stays the same, as in 200 V.
I don't follow. Someone care to explain?

Thanks in advance,

Where is it said such a thing?
 
It was in a physics problem concerning conductors. But I just found out that its because the voltage source works against the work done when moving the plates. A current is created and the extra voltage created does the work. So the voltage between the plates should stay the same to a certain point.
