Discussion Overview

The discussion revolves around the reasons for the decrease in electrical potential in the context of capacitors. Participants explore different aspects of potential, including electric field potential and potential energy, and consider factors such as leakage and charge distribution in capacitors.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant requests clarification on which type of potential is being referred to—electric field potential or potential energy.
  • Another participant suggests that the decrease in voltage over time is due to leakage, which they attribute to imperfections in insulation.
  • A participant specifies that the discussion is about electrical potential decrease.
  • One participant describes a parallel plate capacitor connected to a battery, explaining that as charge moves from the positive plate to the negative plate, there is a change in voltage, which they interpret as a decrease in voltage.

Areas of Agreement / Disagreement

Participants express differing views on the specific causes of potential decrease, with some attributing it to leakage and others discussing charge movement. The discussion remains unresolved with multiple competing perspectives.

Contextual Notes

There are limitations regarding the definitions of potential being discussed, and the implications of leakage and charge movement are not fully explored or agreed upon.

Please make the question little more clear, what potential are you talking about is it electric field potential or potential energy.
 
Dear Lakshmi,

The Decrease In Voltage Over Time Is Due To Leakage, Ie Imperfections In Insulation.

it is the electrical potential decrease
 
Let a parallel plate capacitor, Both plates are connected to diffrent terminals of a battery. On the plate connected with the positive side of the battery there is a positive charge and voltage V(+) similerly on the other plate there is a negative charge and voltage V(-).
As one move from the one of the plate to other there will be change in voltage, usually charge is assumed to move from positive to negative side, Voltage is decreased.
