Electric Field Unchanged in Parallel Plate Condenser w/ Varying Distance

Click For Summary
SUMMARY

The electric field in a parallel plate condenser remains unchanged when the distance between the plates is increased, as demonstrated in the discussion. Initially set at 4mm with a potential difference of 60 volts, increasing the distance to 12mm results in a potential difference of 180 volts. According to the formula E = V/D, the electric field's magnitude is determined by the charge density on the plates, as established by Gauss' law, indicating that the electric field is independent of the distance between the plates in an ideal scenario.

PREREQUISITES
  • Understanding of electric fields and potential difference
  • Familiarity with parallel plate capacitors
  • Knowledge of Gauss' law
  • Basic grasp of the formula E = V/D
NEXT STEPS
  • Study the implications of Gauss' law on electric fields
  • Explore the behavior of electric fields in non-ideal conditions
  • Investigate the relationship between charge density and electric field strength
  • Learn about capacitance and its dependence on plate separation
USEFUL FOR

Physics students, electrical engineers, and anyone interested in understanding the principles of electric fields and capacitors.

If the distance between the plates of a parallel condensor is 4mm and the potential difference is 60 volts . Now if we increase the distance between the plates to 12mm , then

Why the electric field does not get decrease , instead of that potential difference between the condensor becomes 180 volts

As we know E= V/ D

For the electric field's magnitude of the plane, where the charges are uniformly distributed, just depends on the density of charges of the plane, which can be acquired from Gauss' law, the electric field won't vary due to the distance in theory.
