What are the basic concepts in electrostatics and is it better to study magnetism and electrostatics connected?

which aal other portions can have a link with electrostatics?

electrostatics delas with charges at rest and  electric field, electric potential and electric potential energy due to such charges.

the basics of electrostats starts with coloumbs law. then gauss law and then capacitors.

magnetism is related to current electricity more than with electrostatics so u can study them seperately.
