Physics · Electrostatic Potential
हिन्दीConsider the following four statements regarding energy stored in a parallel-plate capacitor with plate area \( A \) and separation \( d \): (A) The electrostatic potential energy is stored in the electric field between the plates. (B) The volume of the region where the electric field exists is \( A d \). (C) The electrostatic energy density per unit volume is proportional to \( E^2 \). (D) Electrostatic force is non-conservative, which is why energy is dissipated when charges are built on the plates. How many of the above statements are correct?
Correct answer · Option 3
Only three
Explanation
Statements (A), (B), and (C) are correct. Statement (D) is incorrect because electrostatic force is conservative, which is the foundational reason why work done is stored as recoverable potential energy.
