Charge
... Electrical Shielding • The electric field inside any charged conductor is zero. • The exact charge distribution over the surface is such that E-field inside is 0. If it weren’t, then the free electrons inside would move under the net force, until they feel 0 net force i.e until E-field was 0. Note, ...
