Physics · Electrostatic Potential
हिन्दीIn a parallel plate capacitor of finite plate area \( A \) and separation \( d \), the electric field lines bend outward at the edges ('fringing of the field'). Under what condition can this edge effect be safely ignored?
Correct answer · Option 3
\( d^2 \ll A \)
Explanation
When the plate separation is much smaller than the linear dimensions of the plates, i.e., \( d^2 \ll A \), the edge effects (fringing) are restricted to small regions and can be ignored.
