    Capacitor decrease
Click For Summary
SUMMARY

The discussion centers on the decrease in electrical potential in capacitors, specifically addressing the causes of voltage drop over time. Key factors include leakage due to insulation imperfections and the inherent behavior of charge movement between the capacitor plates. When a parallel plate capacitor is connected to a battery, the positive plate accumulates positive charge and the negative plate accumulates negative charge, resulting in a voltage difference that decreases as charge moves from the positive to the negative plate.

PREREQUISITES
  • Understanding of capacitor fundamentals
  • Knowledge of electrical potential and voltage concepts
  • Familiarity with parallel plate capacitor configurations
  • Basic principles of charge movement in electric fields
NEXT STEPS
  • Research the effects of insulation materials on capacitor performance
  • Learn about capacitor leakage currents and their impact on circuit design
  • Explore the mathematical modeling of voltage changes in capacitors
  • Investigate different types of capacitors and their applications in electronics
USEFUL FOR

Electrical engineers, electronics students, and anyone interested in understanding capacitor behavior and voltage dynamics in circuits.

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.
