electric powered field E= - dV /dr As potential is persevering with dV / dr =0 for this reason electric powered field is 0 in a area the place electric powered potential is persevering with. as an occasion, interior a hollow charged matallic sphere, the electrical powered field IS 0 however the flair interior is persevering with and equivalent to potential on the suface of charged sphere
