Electrostatic Potential and Capacitance — Physics STD 12 Science — Question

1. Are closer in regions of large electric fields compared to regions of lower electric fields.
2. Will be more crowded near sharp edges of a conductor.
3. Will be more crowded near regions of large charge densities.

Equipotential surfaces are closer in regions of large electric fields because electric field intensity is inversely proportional to the separation between equipotential surfaces. 
As the electric field intensities is large near sharp edges of a charged conductor or near the regions of large charge densities. Therefore, numbers of equipotential surfaces are closer to such places or in other words they are more crowded.
